Houston Texans rookie defensive end/linebacker Jadeveon Clowney had sports hernia surgery, coach Bill OBrien told the Houston Chronicle on Friday.
Clowney, the former South Carolina star who was the No. 1 overall pick of the 2014 NFL draft, was dealing with a groin injury.
OBrien said Clowney was evaluated in Philadelphia and the team decided the best option was surgery, the Chronicle reported.
He will miss next weeks mandatory minicamp and is expected to return for training camp, which begins in late July.
Clowney last Friday signed a guaranteed $22 million contract with the Texans, which included a $14 million signing bonus.
Texans defensive coordinator Romeo Crennel said earlier this week Clowney was making good progress in learning his new hybrid position.
