CFP selection committee chairman Mack Rhoades has been replaced by Arkansas athletic director Hunter Yurachek following an announcement Thursday that Rhoades had stepped down from the role and taken a leave of absence as the athletic director at Baylor while the school investigates unspecified allegations against him.

While not going into additional details, Baylor vice president Jason Cook said Thursday the allegations against Rhoades do not involve Title IX, student-athlete welfare or NCAA rules violations, and do not involve the football program. Cook said the university takes the allegations seriously and is in the process of conducting a thorough investigation.

The school earlier in the day released a statement that said Rhoades began his leave for “personal reasons” on Wednesday.

Rhoades didn’t respond to a message from The Associated Press. He told ESPN that he initiated his leave from Baylor, but declined to explain why.

The new allegations received this week are not related to a report earlier this month of an alleged verbal and physical altercation involving Rhoades, a football player and an assistant coach. The school had previously said it reviewed and investigated that matter, and that it was closed after appropriate actions were taken.

Rhoades was in the second year of a three-year College Football Playoff selection committee appointment, and his first season as chairman.

Yurachek, in his second year on the committee, now becomes the primary spokesperson for the CFP decision making process. The chairman regularly appears on weekly prime-time ESPN reveals of the rankings.

Utah AD Mark Harlan will fill Rhoades’ vacancy on the committee as the Big 12 representative. Harlan previously served a term in 2023.

The selection committee was already down from its standard 13 members to 12 after Randall McDaniel stepped away from his role on the committee for personal reasons last month.
