OAKLAND -- Three Raiders players left Sunday's 15-0 victory over Kansas City due to injury and did not return.
Cornerback Phillip Adams suffered a concussion on a second-quarter tackle of Jamaal Charles for a three-yard loss. It was Adams' second concussion in as many weeks, as he was concussed on an interception of Cleveland's Brandon Weeden on Dec. 2.
Rookie receiver Juron Criner suffered a hip injury early and Mike Mitchell re-aggravated his neck injury.
"He was actually cleared to go back in the game," said Raiders coach Dennis Allen. "I just chose not to put him back in the game."
Receiver/punt returner Denarius Moore left for a spell in the second half with leg cramps, but returned.
