NORMAN, Okla. (AP) Oklahoma's quarterback situation is not as settled as it seemed.

The Sooners are seeking a replacement for Heisman winner Baker Mayfield, and Kyler Murray and Austin Kendall are the top candidates for the job. Murray was the backup last season while Kendall redshirted. Based on Murray's outstanding work last season, it seemed he was the clear front-runner. Oklahoma coach Lincoln Riley said that's not the case.

"Austin has started to settle in this last half of spring," Riley said after the spring game. "He's played really well. He did a lot of nice things today. It's neck-and-neck right now without a doubt."
