Oklahoma State freshman safety Joe Mitchell has been sent home amid allegations that coaches at his high school might have tampered with his academic transcripts.
Those allegations have left three of Mitchell's football coaches at Morton Ranch High School (Katy, Texas) near Houston, including his head coach, on administrative leave with the school district.
Oklahoma State officials allowed Mitchell to practice Monday, but decided to send him home as his transcripts were scrutinized by the NCAA clearinghouse.
"Joe Mitchell is heading back to Houston," Oklahoma State coach Mike Gundy told reporters after practice Tuesday. "He's got some personal issues he's got to take care of. We learned more today about it. I'm not sure anybody knows, in detail, where they're at.
"But as for now, he has to work through those issues before he can come back here. Hopefully, it could be within the next few weeks. If not, then we'd certainly like to get him back in January."
Mitchell was a quarterback and a safety at Morton Ranch, producing 63 tackles and four interceptions as a senior. He likely would have been redshirted with the Cowboys if he had remained in their program this season.
The Houston Chronicle reported that an investigation began when Katy administrators were told by Texas' University Interscholastic League that three Morton Ranch coaches might have violated district policies, including student records, possible misuse of funds and eligibility.
