Idk honestly. But teams do sometimes have a player go for a game or two to see how he plays when they're not sure about the problem. There's no way to know how it went down and the Rams are notoriously tight lipped on this shit.But why? You got preseason to do stuff like this. I honestly doubt they knew the full extent of the injury. Players often try to hide injuries to stay on the field in hopes to play through it.
