Charles Barkley is all in on Oklahoma for the College Football Playoff.

Barkley showed up rocking a Sooners jersey Thursday night on the NBA on TNT set.

It is unclear exactly why Barkley is supporting Oklahoma. Perhaps the Auburn alumnus is a tad bitter about that SEC Championship Game in which Georgia pounded his alma mater 28-7.

“Baker Mayfield, I’m counting on you, my brother,” Barkley said.

Ernie Johnson, who hosts the show, also was rocking his school’s jersey — along with a bow tie — during the broadcast.

Johnson said he is a 1978 Georgia grad. His presence helped ease Barkley’s trolling attempt.
