Jadeveon Clowney, who underwent surgery for a sports hernia two weeks ago that caused him to miss minicamp, played with the injury during his final season at South Carolina, according to a report.

Clowney had said earlier this month that the injury did not predate his time with Houston, but his agent told a different story to NFL.com during Thursday's NFL rookie symposium.

"He thought about not participating in his pro day but went ahead anyway, and what a performance," Clowney's agent, Bus Cook, told the website.

Cook says Clowney thought he was dealing with a groin injury.
