Cooper Kupp Suffers Setback With Hamstring Injury, Status Uncertain for Rams' Opener

Kupp originally injured his hamstring early in training camp.
He recently experienced a muscle strain setback in his recovery.
Kupp missed the final eight games last season due to an ankle injury.
His presence is crucial for the Rams' passing offense and quarterback Matthew Stafford.
If Kupp can't play, receivers Van Jefferson and Allen Robinson would take on bigger roles.
