Welker down, doesn't look good

New England Patriots slot receiver Wes Welker is hurt, and it looks serious.

Welker suffered an apparent left knee injury while making a cut after catching a pass in the first quarter. Patriots quarterback Tom Brady and receiver Randy Moss were among those who knelt over him on the field. Welker was helped off the field then taken to the locker room on a cart.

Welker leads the NFL with 123 receptions and has been the Patriots' MVP.
