Will J.J. Watt be recovered from back surgery in time for Week 1?
That's the question hanging over the Houston Texans' preseason in an AFC South that suddenly seems hyper-competitive.
Although Watt has yet to miss a game in his five-year career, coach Bill O'Brien recently acknowledged to ESPN's Ed Werder that the Texans are still unsure if the three-time Defensive Player of the Year will be available for the first two regular-season contests.
As the transcendent defensive force of his generation, Watt is widely viewed as the NFL's most valuable non-quarterback. Houston's chances of winning a pair of home games versus the Chicago Bears and Kansas City Chiefs take a sizable hit if Watt doesn't suit up.
