The Minnesota Vikings lost star running back Adrian Peterson to a devastating knee injury last week and starting quarterback Christian Ponder was knocked out of the game with a concussion. But Ponder has responded well to concussion tests this week and he has been a full participant in practice, so it appears he will be all set to start against the Chicago Bears this weekend.
Elsewhere on Minnesota's Thursday injury report, cornerback Asher Allen (shoulder/concussion) and defensive back Benny Sapp (shoulder) also fully participated in practice. Cornerback Chris Cook missed his second straight day of practice for reasons unrelated to injury. Offensive guard Anthony Herrera (lower back) was limited, as was safety Jamarca Sanford (shoulder). Herrara was held out of practice on Wednesday.
