Arizona State quarterback Steven Threet still hasn't been cleared to participate in spring practices, which start March 22.
Threet, a senior who started 11 games last year, suffered three concussions this past season, coach Dennis Erickson said.
"I don't know if he'll play spring football," Erickson said.
Threet briefly spoke to the Arizona Republic about his status at the end of January.
While Erickson described his quarterback competition as "wide open," it would appear that junior Brock Osweiler now owns the inside track to the starting job in 2011.
Osweiler replaced Threet early in the UCLA game -- and threw for 380 yards and four touchdowns in a 55-34 win -- and then led the Sun Devils to a victory over rival Arizona.
Threet completed 62 percent of his passes for 2,534 yards with 18 touchdowns and 16 interceptions in 2010. Osweiler completed 57 percent for 797 yards with five touchdowns and no interceptions. While their efficiency ratings were nearly identical, Threet's tendency to throw interceptions and Osweiler's ability to avoid doing so was a chief reason many saw Osweiler as the favorite to win the job, no matter Threet's health.
Erickson also said four other players will be out or significantly limited this spring due to shoulder injuries: defensive end Junior Onyeali, safety Eddie Elder, safety Keelan Johnson and receiver Mike Willie.
