UCLA cornerback Marcus Rios will undergo a sinus procedure this week and will miss Saturday’s game against Arizona State.
Rios, a freshman, has been suffering from migraine headaches for three weeks. He has had similar sinus problems in the past.
The Bruins have used Rios in five games as a backup to starters Aaron Hester and Sheldon Price, both seniors.
Fabien Moreau, another freshman, is the only backup who has played cornerback this season. Safety Andrew Abbott has played cornerback in the past.
Whether Rios can return for the Arizona game on Nov. 3 remains to be seen. He is the second freshman cornerback the Bruins have lost. Ishmael Adams underwent shoulder surgery in September and is out for the season.
