LB Mayo injures left knee

OAKLAND -- Patriots linebacker Jerod Mayo suffered a left knee injury midway through the second quarter. His return is questionable.

Mayo needed attention on the field before being aided off the field by two trainers.

Veterans Tom Brady and Kevin Faulk were among those that came over to check on his health on the sideline. Mayo took off his wrist tape, which seems to suggest he's not coming back any time soon.

Mayo was unable to walk off the field with his teammates at halftime and was instead carted from the field.

Linebacker Gary Guyton took over the green dot as the player receiving calls from the sideline.
