Houston Texans defensive end Jadeveon Clowney said Thursday that he sustained a concussion in practice last month but was cleared to play a week later, according to the Houston Chronicle's John McClain.
Clowney was injured on a helmet-to-helmet hit in a joint practice with the Denver Broncos on Aug. 20. The team never disclosed his injury but said he'd be ready for Week 1. Clowney didn't play in the Texans' preseason game against the Broncos on Aug. 23 or in the team's final preseason game against the 49ers on Aug. 28, even though he says he had been cleared by then.
The No. 1 overall pick in this year's draft, Clowney returned to practice Wednesday and will play in Houston's season opener Sunday.
Clowney also had hernia surgery in June.
The 6-foot-5, 266-pounder was a two-time All-American at South Carolina, where he had 24 sacks and 47 tackles for loss over three seasons.
The Texans open the season against the Washington Redskins at home.
