Adrian Peterson has made an improbable return from major knee surgery and has rushed for 153, 123 182 and 171 yards rushing over the past four weeks.

Peterson believes his recovery is ongoing and isn't 100 percent back to his pre-injury strength.

"Last week in Seattle, on one run, I felt scar tissue break up around my patella tendon on one of my cuts,'' said Peterson. "That's part of the recovery, that scar tissue breaking.''
