The Vikings lost starting right guard Anthony Herrera for the season to a knee injury. Herrera was hurt in the first quarter of the game against Green Bay and didn’t return. He was replaced by Ryan Cook. Coach Brad Childress said he was “very disappointed” for Herrera and that he believed he tore his anterior cruciate ligament. Herrera will have an MRI test Monday to confirm the diagnosis.

Arizona linebacker Will Davis was carted off the field with an ankle injury. Davis sat up in the cart as he was taken away. He was injured in the fourth quarter against Kansas City. And wide receiver Early Doucet took a blow to the head in the second quarter and left the game with what coach Ken Whisenhunt described as a concussion.

In other games: Jets right tackle Damien Woody left New York’s win over Houston with a knee injury and didn’t return; Bengals CB Johnathan Joseph hurt his ankle and missed the second half; and safeties Roy Williams (concussion) and Chris Crocker (right knee) also left in the first half of the loss to the Bills.
