Stunner: Stoops Abruptly Retires

NORMAN, Okla. (AP) — Bob Stoops had been the longest-tenured active head football coach. Not anymore.

Stoops has retired after 18 seasons at Oklahoma. Stoops was 190-48 with the Sooners, winning 10 Big 12 titles and the 2000 national championship.

The 56-year-old Stoops says the time is right to step down, but adds his health had nothing to do with his decision.

The Sooners moved quickly to name a replacement, elevating offensive coordinator Lincoln Riley. The 33-year-old Riley becomes the youngest head coach in the Bowl Subdivision.
