Watt has back surgery, expected to miss rest of season (Yahoo Sports)

A person familiar with J.J. Watt's condition said the Houston Texans' star defensive lineman had back surgery Thursday and is expected to miss the rest of the season. Watt was placed on injured reserve Wednesday with a back injury. It's his second back surgery in two months after he missed training camp and Houston's four preseason games after surgery in July to repair a herniated disk.
