Los Angeles Rams wide receiver Cooper Kupp sustained an ankle injury during the second quarter of their Week 2 game against the Arizona Cardinals and is doubtful to return. Kupp was tackled while making a catch and was seen limping as he walked to the locker room at halftime, where he did not return for the second half. He finished the first half with four receptions for 37 yards. The Rams are already without fellow wide receiver Puka Nacua, who is on injured reserve due to a knee sprain, leaving the team with a thin receiving corps. If Kupp is unable to play moving forward, Demarcus Robinson, Tyler Johnson, Tutu Atwell, and Jordan Whittington are expected to fill the gap. The situation presents a significant challenge for the Rams, who were trailing 24-3 at halftime when Kupp was injured.
