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.
The Patriots have placed Rob Gronkowski on injured reserve, officially ending the injured tight end's season.
The Patriots have added running back D.J. Foster to the 53-man roster.
Gronkowski underwent surgery on his back Friday in Los Angeles. There was some hope he might be able to return if the Patriots reached the Super Bowl, but this move ends that.

ALAMEDA -- The Oakland Raiders have signed DL Branden Jackson to the active roster and placed CB DJ Hayden on the Reserve/Injured List, the club announced Saturday.
Jackson originally signed with the Raiders as an undrafted free agent on May 16 of this year after participating on a tryout basis at the team’s rookie mini-camp. After participating in the offseason program and training camp with the team, he was waived on Sept. 3 and signed to the practice squad the next day, where he spent the first 12 weeks of the regular season.
The 6-foot-4, 268-pounder played four years at Texas Tech, seeing action in 51 games with 38 starts. Jackson totaled 138 tackles (97 solo), 11 sacks, three forced fumbles, two fumble recoveries and seven passes defensed.
