Former Arizona head coach Mike Stoops is headed back to Oklahoma to join his brother, Bob.

Stoops served as the co-defensive coordinator for the Sooners from 1999 to 2004 and helped Oklahoma win the 2000 National Championship. He’s spent the past seven-plus seasons at Arizona.

Stoops return to Norman throws into question the future of defensive backs coach Willie Martinez and possibly current DC Brent Venables.

The university has not yet confirmed Mike Stoops' hiring or any other changes to the football staff.
