MINNEAPOLIS -- For the third straight off-season, Adrian Peterson will be recovering from surgery. KWaun Williams Super Bowl Jersey . The Minnesota Vikings said their star running back had an operation Thursday to repair his adductor muscle, which is part of the groin. The team said Peterson was expected to be fully recovered in about six weeks, giving him plenty of time to heal before off-season workouts get going. The procedure was performed by Dr. William Meyers at the Vincera Institute in Philadelphia. Peterson rushed for 1,266 yards in 14 games, missing two in December due to a sprained right foot. The groin problem was lingering long before that, though, sapping him of some of his explosiveness. He acknowledged after a loss at Seattle Nov. 17 that the injury was bothering him "a lot." Peterson gained only 65 yards on 21 carries that afternoon, albeit against the leagues best defence. He still managed, two weeks later, to rush for 211 yards against Chicago, the fourth-highest total of his career. But then came the sprained foot in the snow Dec. 8 at Baltimore, and he played only once more, and not at full speed. He tallied 45 yards on 11 attempts at Cincinnati on Dec. 22 and said afterward he felt uncomfortable, a rare admission for one of the sports most confident and determined players. Keeping him off the field is always hard. "Thats just not my mentality, leaving these guys out to dry, just because, what the heck, my passion for the game," Peterson said last month. "I love the game too much to sit out just because. If Im out, youre going to know that he cant go." Peterson is 27th on the all-time rushing list, second only behind Steven Jackson among active players, and he has often stated his goal of someday passing Emmitt Smith for first place in history. Peterson will be 29 before the 2014 season starts, though, which means he is already in the later part of his prime. His punishing running style and the nature of playing such a taxing position will make it difficult, even for him, to keep the pace. This was Petersons third, though least invasive, surgery in the last 25 months. He had anterior cruciate and medial collateral ligament reconstruction in his left knee in December 2011. Then, after rushing for 2,097 yards and winning the NFL MVP award, Peterson had a procedure done in February 2013 to repair a sports hernia in his abdomen. Meyers performed that surgery, too.

Major League Baseball says its virtually certain all the new systems will be in place for opening day. MLB Executive Vice-President Joe Torre met with general managers Tuesday and said he expects approval from owners, players and umpires by January. "We expect to be all on the same page by the time we need to have it," he said. Virtually all umpires calls other than balls and strikes, checked swings and some foul tips will be reviewable. The system was tested last week during Arizona Fall League games, with two major league umpires reviewing video and making the final call. Owners are expected to give their go-ahead Thursday for funding and then approve the rules when they meet in January. "Im sure theyll do as much testing as they think is feasible, but ultimately theyll probably go with what they have," New York Mets general manager Sandy Alderson said. "There probably will be bugs. ... It might be a little rough at the beginning, but I think that things will work out thereafter." Baseball started using video review in 2008 but limited it to home run calls -- whether a ball went over a fence or was fair. Under the system thats been in placce, three of the four umpires at a ballpark watched video provided them by MLB. Robbie Gould Super Bowl Jersey. Starting next year, challenged calls will be reviewed at a central location. "Wed like to have everything clean and be incorporated into the challenge system," Torre said. Most reviews during the Arizona test averaged 1 minute, 40 seconds. Torre expects the new system will be used at some but not all spring training sites. "We have to make sure the managers have a chance to practice with this. They need practice only because its never been done before," he said. "Youre not going to be able to test it everywhere because you just cant put the equipment everywhere." On another matter, Torre said there will be no change to baseballs obstruction rule, which gave St. Louis a controversial 5-4 win over Boston in Game 3 of the World Series last month. Cardinals runner Allen Craig tripped over Boston third baseman Will Middlebrooks in the ninth inning of a tied game and was awarded home plate on obstruction -- intent is not a factor in the obstruction decision by umpires. "I really dont see anything" to be done, Torre said, before adding: "Nobody wants a game to end like that. I dont think thats any secret." ' ' '
