The Oklahoma Sooners made their road to the College Football Playoff a lot more difficult on Saturday, losing to heated rival Texas 48-45 in the Red River Showdown.

Though the Big 12 isn’t exactly known for strong defenses, that terrible performance from the Sooners was apparently the last straw.

According to a report from 247Sports, the decision has been made to relieve DC Mike Stoops of his duties:

Mike Stoops is out as OU’s defensive coordinator, has been able to confirm. His replacement isn’t yet official, as a source said “Riley will make that known soon.”

Following the latest poor defensive performance, the much-maligned coordinator met with head coach Lincoln Riley and OU President James Gallogly to have a serious discussion. It turns out that serious discussion ended up being the decision that Stoops is out.

Stoops has been Oklahoma’s defensive coordinator since 2012, but there have been a number of bad Oklahoma defensive performances in recent years.

Stoops’s brother, Mark, currently serves as Kentucky’s head coach.
