Los Angeles Rams WR Cooper Kupp Kyle Terada-USA TODAY Sports

Cooper Kupp’s injury-riddled season continued Sunday as he left the Los Angeles Rams’ game early and did not return.

Kupp limped off the field during the second quarter of Sunday’s contest against the Seattle Seahawks. He was formally ruled out about an hour after suffering the injury, which the Rams characterized as an ankle issue.

While there were few specifics on the injury, Kupp was obviously in severe pain on the sideline before limping to the locker room.

Kupp had a worrying hamstring issue that cost him the first portion of the season. Even after returning, he has been relatively quiet, making a modest 23 catches for 364 yards and one touchdown in five games coming into Sunday.

Since his dominant 2021 season, Kupp has struggled to stay healthy and productive. It remains to be seen if this injury lingers, but his 2023 campaign is looking to be another underwhelming one.
