ALAMEDA https://www.raiderslockerroom.com/authentic-derek-carr-jersey , Calif. (AP) — Star receiver Antonio Brown was sent away from the Oakland Raiders four days before the season opener amid reports he could be suspended over a confrontation with general manager Mike Mayock.Mayock said at the beginning of practice Thursday that Brown wasn’t at the Raiders facility and wouldn’t be practicing a day after posting a letter from the GM on social media detailing nearly $54,000 in fines.“I’ll make it short and sweet,” Mayock said. “Antonio Brown is not in the building today, won’t be practicing. I don’t have any more information for you right now. When I have some and it becomes appropriate you guys will all get it. But that’s it for today.”ESPN reported earlier Thursday that the two had a confrontation the previous day over the posting of the letter and that the Raiders plan to suspend Brown. Teams have the right under the collective bargaining agreement to suspend players up to four games for conduct detrimental to the team.A suspension would also void the more than $29 million in guarantees over the next two seasons contained in Brown’s contract with the Raiders.“I’m not going to get into any of that stuff right now,” coach Jon Gruden said. “We’ll have an official announcement later.”Gruden said he was frustrated by the situation but that the team is ready to start the season without Brown if necessary. The Raiders spent most of training camp without Brown on the field as he dealt with frost bite on his feet and a fight with the NFL over his helmet.“We’ve been going out for practice every day and we adjusted without him,” Gruden said. “We never knew sometimes when he was going to practice. So we’re good at it. We’re good at adapting and adjusting. Unfortunately. I’m going to keep my fingers crossed.”Brown’s agent, Drew Rosenhaus, told NFL Network that he has been in contact with the Raiders and Brown and hopes to be able to avoid a suspension.“My objective is to get things worked out between Antonio and the Raiders so he can fulfill his contract and do what they brought him in to do,” Rosenhaus told the network. “I don’t think it’s too late to salvage that relationship.”This is just the latest development in a dramatic first season in Oakland for Brown, who has yet to step on the field for a game with his new team.The Raiders acquired the game’s most prolific receiver after he wore out his welcome in Pittsburgh. Oakland gave up only a third- and fifth-round pick for the four-time All-Pro receiver and gave him a hefty raise with a new three-year contract worth $50.125 million.But Brown was unable to practice at the start of training camp after getting frost bite on his feet during a cryotherapy accident in France.Brown was activated July 28 and took part in one walkthrough and part of one practice before leaving the team to get treatment for his feet and to fight the NFL and the NFLPA over his helmet.Brown lost two grievances with the league in his attempt to use an old helmet now banned for safety reasons. He skipped practice on Aug. 18, prompting Mayock to issue an ultimatum for Brown to be “all in or all out” and also to hand him a $40,000 fine.Brown returned to the team the following day but then missed a mandatory walkthrough before an exhibition game in Winnipeg on Aug. 22, leading to a second fine of $13,950.Brown publicized those fines on his Instagram account Wednesday. Brown also wrote on the account: “WHEN YOUR OWN TEAM WANT TO HATE BUT THERE’S NO STOPPING ME NOW DEVIL IS A LIE. EVERYONE GOT TO PAY THIS YEAR SO WE CLEAR.”That apparently prompted the latest run-in with Mayock and now leaves Brown’s status with the team in doubt ahead of Monday night’s opener at home against the Denver Broncos.“I think moving forward everything can work out,” Rosenhaus said. “We’ve had some bumps in the road but he’s had an incredible career. We had some setbacks recently but I’m confident we can get back to doing the great things that the Raiders signed him to do. That’s my intention.”Brown had several issues in Pittsburgh as well, leading to the team’s decision to trade him even though he topped 100 receptions and 1,200 yards receiving in each of the past six seasons.The relationship reached a breaking point in late December. Steelers coach Mike Tomlin benched Brown during the regular-season finale against Cincinnati after the wide receiver went radio silent in the final 48 hours before the game.Brown arrived in a fur coat, hung out for a half and then disappeared from view until well after his teammates had cleaned out their lockers following a 9-6-1 finish that left Pittsburgh out of the playoffs for the first time since 2013.When Brown did resurface Derek Carr Jersey White , he began engaging in a series of increasingly antagonistic acts designed to expedite his departure. He went on Instagram with former Steelers linebacker James Harrison during Tomlin’s season wrap-up press conference. He decried quarterback Ben Roethlisberger’s “owner’s mentality” and chastised Tomlin for disciplining him in Week 17. KANSAS CITY, Mo. 鈥斅燩atrick Mahomes stalked Chiefs wide receiver Damarcus Robinson on the sideline as chants of “MVP” echoed throughout Arrowhead Stadium, trying to track down a football that would serve as a keepsake not only of this night but of this season.The first-year starter had just thrown an 89-yard scoring strike to Robinson, the 50th time one of his passes ended up in the end zone. It also gave Mahomes more than 5,000 yards passing, not to mention put a dagger in Oakland and clinched the AFC West title and No. 1 seed in the playoffs.“They’re special,” Mahomes said after securing that memento, and after Kansas City had wrapped up a 35-3 whitewash of the Raiders on Sunday. “To do those things in this league, that doesn’t happen.”Not very often anyway.Mahomes finished with 281 yards passing, the highlights the strike to Robinson and a 67-yard TD pass to Tyreek Hill. That gave him 5,097 yards and 50 touchdown passes, and allowed Mahomes to join Peyton Manning as the only QBs to hit 5,000 and 50 in the same season.“This team, we love each other. We root for each other. And that’s why we’ve had so much success,” said Mahomes, who already had shattered just about every franchise passing record.Hill finished with five catches for 101 yards, becoming the Chiefs’ single-season leader for yards receiving with 1,479 Antonio Brown Raiders Jersey , while adding a fourth-quarter touchdown run. Damien Williams added 51 yards and a score on the ground as the Chiefs (12-4) beat the Raiders for the eighth time in nine games.The decisive win came after Kansas City squandered a chance to clinch the division with a fourth-quarter collapse against the Chargers and again in a shootout loss last weekend in Seattle.“This was a tricky game,” Chiefs coach Andy Reid said. “We felt like we let off the accelerator there lately and we didn’t take advantage of opportunities.”No problem with that on Sunday.Derek Carr had his league-leading streak of 332 passes without an interception snapped when the Chiefs’ Daniel Sorensen returned a pick for a touchdown in the first quarter. Carr threw another pick and lost a fumble as Oakland (4-12) turned the ball over on its first four possessions.He finished 23 of 32 for 184 yards, and Doug Martin ran for 100 yards but also lost a fumble, as the Raiders headed into an offseason of uncertainty surrounding where they will play next season.“Obviously, we got a lot a work to do,” said Raiders coach Jon Gruden, who wrapped up his first season back with the franchise. “I know today was not a good note, but it’s a great group of guys who laid quite a foundation and I think we can build on that. I’m excited about that.”The Chiefs eliminated any drama in the first 20 minutes.Mahomes started the scoring barrage when he threw a perfect post pass to Hill, who waltzed into the end zone for his long touchdown reception. And a few minutes later, Sorensen stepped in front of tight end Jared Cook 鈥?who had inexplicably stopped his route 鈥?for a 54-yard pick-6.The Chiefs defense kept causing turnovers, and Williams capped another effortless drive with a short touchdown run, giving Kansas City a comfortable 21-0 lead late in the first half.“This was a tricky game,” Chiefs coach Andy Reid said, “and the guys took care of business.”The league’s highest-scoring offense continued its onslaught after the break.Mahomes delivered the clincher when he floated a pass deep downfield to Robinson, who ran out of the grasp of his would-be tackler. Robinson was so far ahead of the defense that he turned around at the 15-yard line and backpedaled into the end zone 鈥?getting a taunting call as his reward.Not that it mattered for the Chiefs, who were already celebrating their postseason bye and what they hope is a Super Bowl road through Arrowhead Stadium. Hill merely added to the party when he added his rushing touchdown in the fourth quarter to put the game away.“We’re all trying to reach a goal,” Hill said, “and that’s the Super Bowl. Head down Womens Bo Jackson Jersey , and we’re all focused, man. Like I said, it feels great, but right now, I just want to win the Super Bowl. We just want to win the Super Bowl.”100View Gallery Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj MehtaKELCE’S CATCHESThe Chiefs’ Travis Kelce had five catches for 62 yards, giving him 1,336 yards this season. That broke the NFL record for tight ends set by the Patriots’ Rob Gronkowski in 2011, only for the 49ers’ George Kittle to pass him a few minutes later. “The individual accolades in this game alone, I think, are a bit overrated,” Kelce said. “You’ve got 11 guys out there trying to push for one goal and sure enough, we achieved that as a team.”MORE RECORDSMahomes was 14 of 24, giving him a franchise-record 383 completions this season.
