NFL injury report: Hit on Ryan Williams main concern after loss to Rams

The Arizona Cardinals had their undefeated streak ended in St. Louis on Thursday night at the hands of the Rams, though were much luckier than Jeff Fisher's squad when it came to injuries suffered during the game.

The biggest loss for St. Louis was wide receiver Danny Amendola, who injured his shoulder while attempting a diving catch in the second quarter of the game. He will undergo further tests on Friday to determine if he has broken his collarbone.

On the Cardinals front, running back Ryan Williams left early after taking a big hit from safety Darian Stewart. Though one of their biggest injury concerns remains the status of John Skelton's ankle after Kevin Kolb had an ineffective showing against the Rams defense. Skelton practiced in full this week, likely setting up some quarterback controversy during practice next week.

The Arizona Cardinals will host the Buffalo Bills at the University of Phoenix Stadium next Sunday, with kickoff set for 1:00 p.m. PT with coverage on the CBS Network.
