Oklahoma completed the flip of three-star Oklahoma State quarterback pledge Jett Niu on Wednesday morning following the start of the early signing period.

Niu, a 6-foot-2 quarterback from Lehi, Utah, is ESPN’s No. 73 pocket passer prospect in the 2025 class. Committed to Oklahoma State since September, Niu’s commitment comes two days after the Sooners hired Washington State offensive coordinator Ben Arbuckle and fills a hole in the Sooners’ 2025 class that had remained after four-star passer Kevin Sperry (No. 132 in the ESPN 300) flipped his pledge to Florida State late last month.

“After much thought and reflection, I’ve decided to decommit from Oklahoma State and commit to the University of Oklahoma,” Niu wrote in a statement posted to social media. “I am incredibly grateful for the amazing support and opportunities I received from Oklahoma State and their coach staff. Thank you for believing in me and helping me grow. I’m looking forward to this new chapter at OU and can’t wait to see what the future holds!”

Initially committed to Appalachian State, Niu gave his pledge to Oklahoma State on Sept. 10 over interest from Washington State, Arizona and Arkansas State, among others. Niu’s offer from Washington State notably came with Arbuckle, the Sooners’ new 29-year-old playcaller, and the pair will now land at Oklahoma as the program prepares for potential change with the futures of quarterbacks Jackson Arnold and Michael Hawkins Jr. uncertain in 2025.

Niu emerged as a breakout star in 2023 when he threw for 3,005 yards with 33 touchdowns in his junior season at Utah’s Lehi High School. He led the program to a 9-3 finish with 2,857 yards and 29 touchdowns to 10 interceptions as a senior.

Minutes after Niu’s pledge, Oklahoma lost the commitment of four-star wide receiver Cortez Mills (No. 120 in the ESPN 300) upon his flip to Nebraska Wednesday.

Mills’ exit marks the latest departure from the Sooners’ wide receiver class and leaves Oklahoma without a pass catcher committed in the 2025 cycle. Four-star wide receiver Marcus Harris (No. 138 in the ESPN 300) decommitted from the Sooners on Sunday before giving his pledge to Washington on Wednesday morning. Three-star pass catcher Gracen Harris remains uncommitted after pulling his pledge from the Sooners on Monday.

Oklahoma began the early signing period Wednesday with the No. 16 recruiting in ESPN’s latest class rankings for the 2025 cycle.
