Two types of injuries scare me about both RBs. Intercostals are muscles found between the ribs. Strained intercostals are often too painful to play with. The pain is very much like a broken rib but the area is harder to protect. An actual non-displaced cracked rib is painful and dangerous. Further injury can result in a punctured lung. QBs have been known to play with hairline fractures if they wear a flack jacket and have the ribs taped. It‘s hard to picture a RB doing so. It’s still very painful. The best hope is that the ribs are bruised. If that’s the injury it depends on the pain tolerance of the injured player. All rib injuries seem to heal slowly and are easily aggravated. Might not make it through the whole game.
