OXNARD, Calif. -- Dallas Cowboys defensive end Anthony Spencer is having arthroscopic surgery on his left knee and is likely to miss the rest of training camp. Spencer said he will have surgery Thursday in Dallas and expects to miss three weeks, which puts his return about the same time the Cowboys break camp before their third preseason game at Arizona. "I have a lot of time," Spencer said Tuesday. "I feel like I will definitely be ready before the season gets here." Spencer hyperextended the knee in off-season workouts and said he aggravated the injury in the conditioning test before training camp. He has described the injury as a bone bruise and said the surgery was to clean up some of the tissue around the knee. "We dont think its a very severe thing," coach Jason Garrett said. "We thought getting it cleaned up sooner rather than later was better for him and for our team." The 29-year-old Spencer had a similar procedure in late August in 2008 but missed only one regular-season game. Dallas breaks camp Aug. 16. He was the leading tackler last season and finished a half-sack behind DeMarcus Ware with a career-high 11. Spencer is playing on a one-year contract under the franchise tag for the second straight season. This years deal is worth $10.6 million.

It is a cliché dragged out by fans and pundits regularly when discussions take place around which teams are better than others. Peter Nevill is open to a promotion in Australias batting order ahead of Mitchell Marsh, as the captain Steven Smith and the coach Darren Lehmann ponder how to get the best out of a middle-order duo who are yet to place their stamp on a Test match with the bat.As highlighted by the selection chairman Rod Marshs reference to Jackson Birds batting as a factor in his non-selection, Australia need to find a way to get more out of their lower-order batting on the days when the top five do not make the desired tallies of runs.It was a weakness exploited ruthlessly by Sri Lankas spinners during their recent clean sweep of a Test series, and a South African attack led by Dale Steyn will be eager to do likewise down under, this time with pace. Neither Marsh (averaging 24 after 18 Tests) nor Nevill (20.88 after 15 Tests) have been able to impose themselves, too often opening the door to the Australian tail.While conventional wisdom has it that allrounders tend to bat at No. 6 and wicketkeepers at No. 7, Nevill and Marsh appear stylistically suited in opposite roles. Nevills busy but not overly histrionic batting has been most successful at No. 6 for New South Wales, where he averages 42.73 with six centuries and a highest score of 235 not out.Meanwhile, Marsh is much more of a free-spirited hitter, capable of changing the momentum of a game after the fashion of Nevills predecessor Brad Haddin or, in earlier years, Andrew Symonds. Nevill said he would happily move up the order, should Smith decide this was a better balance for the Test team. Id happily do whatever the skipper asked me to do, Nevill told ESPNcricinfo. Wherevers best for the team Im happy to bat wherever. Your role at No. 7 is either the teams going really well and you need to go out there and look to push the game along with an eye on a declaration.Youre either thhat or five for not too many and you need to go out there and guts it out and put a partnerships together with whoever youve got at the other end, and batting with the tail as well.dddddddddddd So its usually one of those two scenarios Ive found being in the Australian team.For his part, Marsh is aware his place is under plenty of scrutiny going into this week. He is trying to focus on positive thoughts and an aggressive batting plan, the better to exploit his obvious power with the willow. Theres no doubt Im probably under a little bit of pressure, but I think if I go into the week thinking like that Im probably not going to enjoy it, he said.Its a home Test match, Im going to prepare as best as I ever have, and go out there and really enjoy myself and not focus on myself to much. I really just want to play for this team and play to win. Every time you bat you just try to bat as long as you can. For me its more about trying to score runs and being positive, and when Im doing that my feet move better and I get into better positions even to leave the ball, so thats my focus.While indicating an eagerness to hang onto his No. 6 berth, Marsh did agree his seam and swing had evolved to a point that a lower order commission would be plausible in the context of a greater bowling load in the field.I certainly want to remain an allrounder, I bat at six. But if that did come up Id be happy to do it, he said. I feel like my bowlings improved a lot over the last 18 months, and its gotten to a point now where Ive had a few occasions where blokes have gone down and Ive had to step up to the third seamer role. Ive done it before, but I really enjoy batting at No. 6 and want to stay there as long as I can. ' ' '
