EDEN PRAIRIE, Minn. -- Adrian Peterson said his first two days on the practice field went pretty smoothly, after the Minnesota Vikings decision to designate him for return from injured reserve. But coach Mike Zimmer cautioned the Vikings still have plenty to determine before deciding when Peterson would play and how he would be used.Well have to see where hes at in conditioning. Theres so many things to figure out, Zimmer said. I think hes in pretty good shape, but he hasnt sat in meetings for three months. Theres a lot of things to consider.Peterson, who tore the meniscus in his right knee against the Green Bay Packers on Sept. 18, practiced for the second time on Thursday. The running back has said hes shooting to return for the Vikings game against the Packers on Dec. 24, but he has also cautioned he wouldnt play if the Vikings arent in the playoff race, adding it would be pointless to return for games that didnt have postseason implications.Asked on Thursday about the running back saying it will be his decision when he returns, Zimmer said, I wouldnt say it was his decision. I would say its a combination. Well sit down and talk, and the medical people [will weigh in]. Its a lot to do with the medical.Said Peterson on Thursday about the Packers game: That was the goal I had set for [myself], but Im going to continue to take it one day at a time. When that time comes, as a group, well sit down and talk.The 31-year-old running back will have to weigh his future in deciding whether playing this season is worth it. The Vikings hold a team option on Peterson for 2017, with a $6 million roster bonus due in March and $18 million cap hit, but if Peterson were to return to Minnesota next season, it would seem likely to be on a restructured contract.Id be lying to you to say that [the future] is not factoring in [to the decision], he said. In my mind, Im telling myself that its 100 percent healed, but I really wont know until I look and see it from images. So with that, youve got to be smart about how you approach everything.Its not really [about proving myself to the Vikings]. A little bit, but I feel like thus far, Ive proven myself. Ive been doing this for 10 years. Its not the first injury Ive overcame, came back and was still able to be successful. Proving anything to the organization, I dont think I have to do that. I think it speaks for itself.Peterson has been wearing a knee brace in practice the last two days, and though he has typically shied away from using one in games, he said hed likely wear one the rest of this year, as he tries to come back from an operation that can keep players out between four and six months.Its like, Why not? The new titanium braces are superlight, he said. Its a little uncomfortable, because I really dont like anything on my knees. But taking in the situation, Ill wear it.The Vikings tumultuous season means Peterson would be returning to a team that looks noticeably different than the one he played for on Sept. 18. Since Pat Shurmur replaced Norv Turner as the offensive coordinator on Nov. 2, the Vikings have been in shotgun sets two-thirds of the time, with their 247 shotgun snaps ranking seventh in the league in that time, according to ESPN Stats & Information.Peterson said Thursday that some of the Vikings offensive terminology has changed in the switch from Turner to Shurmur, though the core of the offense remains the same. There are a couple wrinkles in there that are a little different, he said. The meeting room is different as well. We have the same offense we had previously, but just with some new twists.Zimmer added he has not yet talked with Peterson about how the Vikings plan to structure his workload. Thats completely up to the medical people what he does, he said.A Peterson return should provide a boost to a Vikings rushing attack thats on pace for the worst rushing average since the New England Patriots in 1994. Peterson had only 50 yards on 31 carries in his first two games, but Zimmer on Thursday attributed many of the issues to the Vikings run blocking and the first two regular-season games in a new system under offensive line coach Tony Sparano.Asked if Peterson could help even if hes less than 100 percent, Zimmer said, Well, I think people will play us differently. Im not saying hes less than 100 percent. Nike Air Max Shoes 2017 China . Woodson said during a radio interview Thursday that the Knicks Carmelo Anthony doesnt get the same calls as other superstars.
