Kupp suffered a low right-ankle sprain during Sunday's 17-16 win over the Seahawks, Ian Rapoport of NFL Network reports.
Kupp reportedly tried to reenter Sunday's contest after initially injuring his ankle, and the fact that he didn't suffer a high-ankle sprain could mean he'll avoid a long-term recovery timetable. The injury does, however, make the veteran wideout's chances of playing Week 12 versus the Cardinals murky. Kupp now has gone four consecutive games without scoring or surpassing 50 receiving yards. If he's forced to miss any time, Puka Nacua and Tutu Atwell will operate as the Rams' top wide receivers.
