Andrew MacDonald Jersey . Watch Kentucky vs. Michigan live on TSN at 5pm et/2pm pt. The winner will move on to the Final Four, a place both squads are very familiar, to battle Wisconsin next Saturday. Kentucky used a determined second-half comeback to down intrastate rival Louisville on Friday night. The Wildcats trailed until the final minutes of regulation, where they grabbed a slim lead and held on to advance. It was the opposite story for Michigan, which played Tennessee in the Sweet 16 two days ago. The Wolverines held a large advantage throughout the contest, but the Volunteers kept chipping away until it was a one-possession game. Michigan didnt let Tennessee complete the comeback though, thus setting up this showdown with the Wildcats. Kentucky leads the all-time series between these two programs, 4-2. The last time the squads met, Michigan pulled out an 81-78 overtime victory back in 1993. John Caliparis Wildcats struggled to find their identity this season, especially down the stretch. But the young squad, made up of mostly freshman and sophomores, got hot at the perfect time, and has beaten teams like defensive powerhouse Kansas State, top-seeded and previously unbeaten Wichita State, and defending national champion Louisville in this tournament. It was a gritty performance versus the Cardinals on Friday, and required some skillful free-throw shooting, particularly in the second half when they went 14-of-16 at the stripe. Freshman star Julius Randle provided yet another double-double in the win, notching 15 points to go with a team-best 12 rebounds. Dakari Johnson and Aaron Harrison each tallied 15 points in the win, and Andrew Harrison tacked on 14 for the Wildcats. Some Louisville foul trouble also helped Kentucky, as Montrezl Harrell and Stephan Van Treese both exited for the Cards after fouling out late. On a team that has a roster full of potential, but very little experience, Randle has stood out as not only a top NBA prospect, but as the teams leader and go-to scorer. He averages a double-double heading into this game, netting 15.1 ppg while bringing down a team-high 10.7 rpg. His .708 free-throw percentage was a big help down the stretch against Louisville. James Young, who fouled out against the Cardinals, is second on the team in scoring with 14.1 ppg, although Aaron Harrison is also averaging 14.1 ppg. His twin brother Andrew Harrison checks in with 11.1 ppg, adding a team-best 144 assists to his stat line. As a team, UK is putting up 75.4 ppg while allowing 66.5 ppg. At one point, Michigan held a 15-point lead in the second half before Tennessee mounted its comeback attempt. The Vols climbed to within one with six seconds left, but Michigans Jordan Morgan drew a foul, which gave the Wolverines a chance to create a bit more separation. Thanks to four players who scored in double figures, the Wolverines were able to fend off the surging Vols, whose Cinderella-like run came to an end in the Sweet 16. Morgan appropriately led the team in scoring with 15 points, adding a team- high seven rebounds in the process. Nik Stauskas had a below-average day shooting (5-of-12 from the field, 3-of-8 from 3-point range), but still chipped in 14 points in the win. Glenn Robinson III added 13 points for Michigan, and Caris LeVert contributed 10 with five assists. As a team, the Wolverines hit 55.1 percent of their total shots. With his 14-point effort on Friday, Stauskas saw his team-leading scoring average take a slight dip. He still nets 17.3 ppg, also adding team-bests in 3-point shooting percentage (.448) and assists (115). Robinson III checks in at second on the roster in scoring with his 13.1 ppg, and LeVert adds 13 ppg. Imagine what the Wolverines would be capable of if they had a healthy Mitch McGary, although Morgan has been nothing less than stellar in this tournament playing the role of the teams big man. Morgan averages a team-high in rebounding (5 rpg), and nets a club-best 69.4 percent of his field goal attempts. As a team, the Wolverines are scoring 74 ppg while giving up 64.8 ppg.

Hazard lasted just 18 minutes in Tuesdays contest before being substituted with the calf problem, and Chelsea manager Jose Mourinho believes he will be without his star winger for at least the next two weeks.

But what advantages does a deflated football hold for a team? Former NFL quarterback Hugh Millen, who played two seasons for the New England Patriots and now helps designs footballs for manufacturer Baden in Washington state, explains.ADVANTAGES OF DEFLATIONNFL rules mandate that a ball must be inflated between 12.5 and 13.5 pounds per square inch. But a football deflated a couple of pounds below the range is softer, allowing for better grip, Millen said.If youre going to be challenged to handle the ball in either very cold conditions or wet conditions, then having the ability to grab the ball and squeeze it, youre going to have more of a chance to remain in contact with the ball, he said.Deflated balls could also mean faster balls thrown by quarterbacks. Because of the softer grip, the index finger remains on the football a tad longer, allowing for faster spirals during a throw, especially for quarterbacks who like to keep their fingers on the seams, Millen said.We know from having put a football in wind tunnels, the faster the ball rotates, the more it cuts through the air. It has less drag, therefore more velocity on the ball, he said, adding later, most quarterbaacks like to have less air than more air. Michael Raffl Jersey. HOW COULD THE REFEREES MISS IT?Referees inspect game balls about two hours before the game, checking the air pressure among other standards. NFL guidelines are clear: a football cannot be tampered after the pre-game inspection.While veteran officials could probably feel a difference between a properly inflated ball and a deflated one, referees arent thinking about ball air pressure during the game since theyve already checked them, Millen said. Theyre busy trying to move the game along.If theyre not of a mindset to check the ball, theyre not engaging their senses, Millen said, adding that some may be wearing gloves.POSSIBLE EXPLANATIONSIn his years in the NFL, Millen said it was common for quarterbacks to ask for balls to be deflated, within the leagues acceptable range, if the footballs felt too hard for their preference. It takes just a couple of seconds to lose 2 pounds of air pressure after inserting a needle. A team equipment staffer could have been careless.Ive seen somebody say, Hey, stick a needle in there for a second just to get the air right, Millen said.Another possible reason: footballs can sometimes leak air. Millen said all football manufacturers produce balls that lose air pressure without tampering. But he adds that would be an easy possibility to test.
