Report: Adrian Peterson's knee shows no signs of swelling
When a player typically comes back from a torn ACL they usually deal with swelling in their knee when they can back on the field and practice for the first time.
According to Jeremy Fowler of the Pioneer-Press, Vikings running back Adrian Peterson hasn’t experienced any swelling in his knee so far, which may help him get on the field for the season opener.
