Houston Texans head coach Bill O'Brien isn't ruling out the possibility of J.J. Watt returning this season, according to Ian Rapoport of NFL.com:
Ian Rapoport#Texans coach Bill O’Brien was asked about the possibility of JJ Watt returning off Injured reserve this season, and it sounds pretty positive: "He's certainly made progress based on his work ethic and who he's working with in the training room. We will see."
Injuries have sabotaged Watt's career in recent seasons, holding him to eight or fewer games in three of the last four years.
