Illinois has found its next coach, hiring Oklahoma State's Brad Underwood after just one year with the Cowboys.

A source told ESPN that Underwood agreed to a six-year deal worth more than $3 million per season. He earned a little more than $1 million per season at Oklahoma State and had four years remaining on his contract.

Fighting Illini athletic director Josh Whitman welcomed Underwood to the program in a tweet Saturday afternoon.

"In searching for a new coach, we were looking for a proven winner who would build upon our proud tradition while developing an unmistakable identity for Illinois Basketball," Whitman said in a statement. "Brad's teams play a fast, aggressive style and show unyielding toughness."

The Cowboys hired Underwood a year ago, and he took the program to the NCAA tournament this season, losing to Michigan in the first round Friday. Previously, he had spent three seasons at Stephen F. Austin, with trips to the NCAA tournament all three years and two first-round wins.
