Happy Thanksgiving to everyone. The Vikings held a practice this morning and although there was no access they did issue an injury report. Guard Anthon Herrera missed a second consecutive day because of a concussion and given the NFL's concern about concussions it will be interesting to see if he plays Sunday.

Fullback Naufahu Tahi must have suffered a setback because after being limited on Wednesday he was held out today due to an ankle issue.

Running back Adrian Peterson was limited again because of an ankle issue. Also limited were wide receiver Bernard Berrian (hamstring) and cornerback Antoine Winfield (foot), who has said he will play Sunday after missing four games.

Linebacker E.J. Henderson (knee) and cornerback Benny Sapp (groin) were able to take part in all of practice for the second consecutive day.

For the Bears, tight end Desmond Clark (neck) was held out of practice after being limited on Wednesday. Guard Roberto Garza (ankle) was limited after not participating on Wednesday. Tight end Kellen Davis (ankle), defensive tackle Tommie Harris (knee) and safety Kevin Payne (back) were able to take part in all of practice.
