NCAA investigates freshman: OSU officials confirmed that the NCAA is investigating the academic transcripts of Joe Mitchell, a first-year freshman safety from Morton Ranch High School in Katy, Texas.

If Mitchell is not cleared by Friday, it is expected that he no longer would be allowed to practice with the Cowboys. Two sources told ESPN.com that Katy Morton officials or coaches may have altered Mitchell's academic transcripts.

"I found out about that (on Monday)," Gundy said. "(Mitchell has) a personal issue that he has to take care of back at home. I don't know all of the details yet. Hopefully, he can get it worked out."
