The problem will be with swelling. Many years ago I played a doubleheader with a badly sprained shoulder and although it was painful and limited my ability to stretch, all I had to do was deal with the pain. HOWEVER, the next day I couldn't get out of bed without help because everything had swollen up and I couldn't function well for weeks. I expect Rondo's elbow will also swell up like a balloon by tommorrow. The training staff deserves a bonus if they can keep the swelling down. You can play with a lot of pain, if the joints are mobile.
