Rams star WR Cooper Kupp (ankle) exits vs. Cardinals

Los Angeles Rams standout receiver Cooper Kupp injured his left ankle in the second quarter of Sunday's 41-10 road loss to the Arizona Cardinals. Kupp was listed as doubtful to return but didn't appear in the second half. He was sporting a boot on the foot as he exited the locker room. Rams coach Sean McVay said he didn't have an update on Kupp's injury. Kupp was injured on his fourth and final reception of the game, a 24-yard gain with 43 seconds left in the first half. He was noticeably limping when he walked off the field at halftime. Kupp had a stellar start to the season last week when he caught 14 passes for 110 yards and a touchdown in a 26-20 overtime road loss against the Detroit Lions. The Rams were already without star wideout Puka Nacua, who injured a knee in Week 1 and went on injured reserve. --Field Level Media
