Rams star WR Cooper Kupp suffers potentially serious leg injury

Kupp immediately grabbed his right leg and was down for an extended period of time. When he was ultimately helped to the bench, he put no weight on his leg. 

Eventually, he had to be taken to the locker room, which he limped to under his own power.

The star wide receiver suffered an injury two weeks ago, but this looks like it could be much more significant.

If Kupp misses time, one might think the Rams could increase efforts to bring back Odell Beckham Jr. However, with the team potentially heading toward a 3-6 start, one has to wonder if they are legitimate contenders at this point, especially without Kupp.
