The Patriots beat the Broncos, 41-23, and clinched the AFC East for the ninth time in 11 years. But they will play their remaining games without Carter, who had 52 tackles, 10 sacks and two forced fumbles in his first season with New England.

The 32-year-old end has 494 tackles, 76 sacks and 17 forced fumbles in 11 NFL seasons, including five each with the 49ers and Redskins.
