Cowboys tight end Jason Witten has left the game with an injury to his jaw. Witten was lit up by 49ers cornerback Nate Clements after making a catch in the third quarter.
Witten has been taking pain-killing injections for broken ribs before every game, but Clements appeared to hit him underneath the chin. Clements wasn't flagged for the penalty. He led with his shoulder, and it looked like a clean play.
In other injury news, rookie cornerback Mike Jenkins has left the game with a right hamstring injury and will not return. Cory Procter has replaced Kyle Kosier at left guard, but Kosier appears to be fine.
The 49ers just made it 32-16, but this game's been over for a long time.
