Adrian Peterson won't play against the Falcons on Sunday. His status on the injury report was changed from doubtful to out this morning before the team left for Atlanta.
Peterson has a high ankle sprain suffered on his left leg against the Raiders last Sunday at the Metrodome.
The Vikings also activated tight end Allen Reisner from the practice squad and waived receiver Stephen Burton to make room for Reisner.
Peterson was unable to do much in limited work off the field yesterday, and it was pretty clear that he wouldn't be able to play. Toby Gerhart will start in his place. With the Vikings at 2-8, it also didn't make much sense to put their star player in danger of a more serious injury.
Tight ends Kyle Rudolph (quadriceps) and Visanthe Shiancoe (hamstring) are both hurting, and Reisner likely will see some action Sunday.
