The injuries are mounting for the Minnesota Vikings, just three days away from the NFC title game.

Defensive tackle Kevin Williams and defensive end Ray Edwards missed their second straight practice on Thursday because of knee injuries.

Edwards had three sacks and five quarterback hurries in last weekend’s win over Dallas.

To make matters worse, receiver and kick returner Percy Harvin also was not present on Thursday. Harvin missed because of a migraine headache, a problem that his plagued him all season long.

Harvin missed a game against Cincinnati in December because of the headaches and visited the Mayo Clinic to address the recurring issue.
