UCLA quarterback Nico Iamaleava will not play Saturday against No. 1 Ohio State because of a concussion, sources confirmed to ESPN.
Iamaleava was injured during last week's loss to Nebraska. He began experiencing concussion symptoms after the game, according to On3, which first reported that Iamaleava would not play.
With Iamaleava out, redshirt sophomore Luke Duncan will make his first career start. Duncan has not attempted a pass in college as he tries to take down the top-ranked Buckeyes.
Iamaleava has thrown for 1,659 yards with 12 touchdowns and 7 interceptions in his first year with the Bruins after transferring from Tennessee.
He led UCLA to three straight wins in October, including a victory over then-No. 7 Penn State, but the Bruins (3-6) have lost two straight and need to win out to become bowl eligible.
