Former first-round draft pick and third-year Seattle Seahawks linebacker Bruce Irvin underwent hip surgery on Monday.

While the Seahawks confirmed Irvin’s surgery, there was no word on which hip was giving him trouble. No other details were immediately available and there was no official timetable for his return, but Irvin said on Twitter that he hopes to be back later this summer.

“Didn’t want this to get out but I’m fine,” Irvin tweeted. “Will (be) back by training camp! For all (you) people saying this (is) a make-or-break year for me! … I’m gon’ get mine! Believe that!”

Irvin, 26, was a surprise pick in the 2012 NFL Draft — few football pundits knew Irvin’s name when Seattle selected him 15th overall. But head coach Pete Carroll and general manager John Schneider quickly assured reporters that Irvin was one of the best pass-rushers available in the draft, and that he could be a difference-maker on the Seahawks defense.

A former West Virginia Mountaineer and a native of Atlanta, Irvin hasn’t been spectacular since he joined the NFL but hasn’t been a bust, either. In fact, he quietly led all rookies in 2012 with eight sacks, collecting 17 total tackles in 16 games.
