Coach Mike Leach announced the resignation Friday. The school said Roc Bellantoni and Darcel McBath will run the defense on an interim basis.

The meltdown against UCLA was one of the biggest blown leads in college football history. Washington State led 49-17 early in the third quarter but UCLA stormed back, scoring seven touchdowns in eight possessions, many fueled by Cougars turnovers. The Cougars followed up by losing 38-13 at Utah last week.
