Oklahoma head coach Bob Stoops is reportedly retiring 'effective immediately'

Bob Stoops is retiring as head coach of the Oklahoma Sooners, according to Berry Tramel of NewsOK.com.

Bruce Feldman of the New York Times confirmed the report, adding that the retirement is "effective immediately."

"Can confirm Oklahoman report that Bob Stoops is retiring at OU, effective immediately," Feldman wrote on Twitter. "Lincoln Riley will become the new HC."

Riley is currently the Sooners' offensive coordinator.

According to Tramel, Stoops, 56, is expected to stay at Oklahoma "in some capacity."

The Sooners went 11-2 this past season, the 18th under Stoops. He was tied with Kirk Ferentz at Iowa as the longest-tenured head coaches in college football.

Oklahoma won ten Big 12 titles under Stoops and one national championship, in 2000. The Sooners won at least ten games under Stoops 14 times and 11 times they ended the season in the AP Top 10.
