Tulane head coach Jon Sumrall has reached an agreement with the school on a contract extension after leading the Green Wave to the conference championship game in his first season.Sumrall had been linked to multiple Power 4 coaching openings but informed Tulane on Sunday night of his decision to stay put.”After working with him and his staff for the past year, I’m convinced that Jon is the right leader at the right time for our football program,” Tulane athletic director David Harris said in a statement Monday. “He brings an incredible combination of leadership, passing, competitive spirit and care for our student-athletes to the job each day.”The Green Wave are 9-4 heading into their Gasparilla Bowl appearance against Florida on Dec. 20. They lost to Army, 35-14, in the American Athletic Championship game on Friday.
