What happened: A knee injury will keep Jadeveon Clowney out of Houston's Week 2 matchup with Cincinnati. He did not participate in any of the Texans' three practice sessions during the week.

Why it matters: The absence removes one of Houston's veteran front-seven additions a month after Clowney completed his Texans reunion. Houston also ruled out Nico Collins and three others for Week 2 on Friday, adding to the club's availability squeeze heading into Cincinnati.

What to watch: Houston's inactive list will show whether more late changes hit the front seven before kickoff. Clowney's first practice participation next week will be the clearest sign of his path back to the lineup.
