Hooker (concussion) has been ruled out for Sunday's game against the Texans, Jim Wyatt of the Titans' official site reports.
Hooker entered the league's concussion protocol following the Titans' 24-18 loss to the Ravens in Week 4. He was held out of practice all week and will observe Sunday's game from the sidelines, so Tony Adams will likely start alongside Kevin Winston at safety. Hooker's next chance to play is Week 6 against the Colts on Sunday, Oct. 18.
