Originally posted by KittleSkittle:The #49ers have some level of optimism concerning LB Kwon Alexander's chest injury. It was not diagnosed immediately as a torn pec, which would be a season-ending injury. He will undergo MRI on Friday to determine the extent of the damage. He appears to have good range of motion.
