The University of Oklahoma Board of Regents approved a two-year extension to football coach Bob Stoops' contract Thursday afternoon.

The action, which extends Stoops' contract through the 2020 season, includes no pay raise or other changes to Stoops' current deal, an OU spokesman confirmed.

Stoops, 52, is set to earn $4.55 million this year, his 15th as the Sooners' coach. Regents last extended his contract in September 2011, when he agreed to a seven-year deal worth $34.5 million before bonuses.

With annual stay bonuses, Stoops' salary was already set to increase to $5.15 million for the 2016-18 seasons.
