UCLA will be without Owamagbe Odighizuwa for the 2013 season after the defensive end had surgery on his right hip Tuesday.
Odighizuwa, who will be a junior this fall, experienced pain in his right hip before spring practice began. He will have two years of eligibility remaining.
UCLA coaches had expected Odighizuwa to replace Datone Jones -- the Green Bay Packers' first-round draft pick -- at defensive end after he posted 44 tackles and 3.5 sacks last season.
Odighizuwa's absence is another hit to a Bruins defense that's experienced key injuries in the offseason. Nose tackle Brandon Tuliaupupu was declared out for the 2013 season after suffering a knee injury during spring practice. Nose tackle Ellis McCarthy and defensive end Sam Tai are still recovering from knee surgeries. Odighizuwa's absence could allow heralded freshman defensive end Kylie Fitts an opening in the line's rotation.
