Riley undecided on Oklahoma's starter vs. TCU: We'll 'see how it goes'

Oklahoma head coach Lincoln Riley said Tuesday the Sooners will "see how it goes" regarding their starting quarterback for Saturday's game against TCU, according to ESPN's Kevin Wilson.

Riley said he hasn't decided if Spencer Rattler or Caleb Williams will start in the Big 12 matchup but expressed confidence in both passers.

"I'm picking between two really good choices that I think can both go play extremely well and have played extremely well," he said.

Riley pulled Rattler, the usual starter, in favor of Williams early in last weekend's Red River Showdown against Texas. Rattler threw for 111 yards and an interception before exiting as the Sooners trailed 28-7 after the first quarter.

Williams scored a 66-yard touchdown run just over a minute into the second quarter and went 16-of-25 for 212 yards and two passing touchdowns as Oklahoma rallied for a 55-48 win. His 300 total offensive yards were the most ever by a true freshman against Texas.

Ranked fourth in the nation in the AP poll and first in the Big 12 with a 6-0 record, Oklahoma has won each of its last four games by seven points or fewer.
