Cooper suffered a torn Achilles during Sunday's 17-14 win at Tampa Bay and will miss the rest of the season, Ian Rapoport of NFL Network reports.
Analysis:Cooper needed to be carted off the field when he sustained the injury early in the second half of Week 4, and the severity now has been confirmed. He thus will end his third pro campaign with 30 tackles, including 3.0 sacks, and one interception in four contests. Isaiah McDuffie will step in at inside linebacker next to Zaire Franklin.
