Injury updates: Arizona, ASU, UCLA and Oregon

Injuries are a drag, but they are one of the key elements of spring football. Avoiding them is not unlike adding a couple of five-star recruits.

  • At Arizona, Ryan Finley reports safety Adam Hall and running back Greg Nwoko will undergo knee surgery next Tuesday. Just last week, former Wildcats co-defensive coordinator Greg Brown -- now running Colorado's defense -- was raving to me about Hall's potential. The prognosis is both players will be out seven months. The Wildcats are deep in the secondary, but Nwoko's loss puts pressure on the backfield, where injury-prone Keola Antolin is the starter.

  • At Arizona State, there's no official word on the severity of knee injuries to cornerback Omar Bolden and receiver T.J. Simpson, but the general feeling isn't terribly positive. Reports Doug Haller, both injuries "are considered serious, and possibly season ending." The Sun Devils probably can find some answers at receiver, and there's experience at cornerback, but replacing a first-team All-Pac-10 cornerback is not easy to do.

  • At UCLA, the news is better. Offensive lineman Jeff Baca, who broke his ankle last week, could return "sometime in August," according to the Orange County Register, which could mean a full-speed return in September. Baca, a fourth-year junior, was a projected starter at tackle.

  • At Oregon, defensive end Terrell Turner, the lone returning starter on the Ducks' D-line, was on crutches with his lower left leg immobilized in a cast. Coach Chip Kelly previously told the Pac-12 blog that Turner would miss spring practice with a "leg" injury, so this is consistent with the pre-spring prognosis. Dion Jordan has stepped in for Turner with the first-team defense.
