Lamar relieved coach Pat Knight of his duties Sunday after a 3-22 record so far this season.
Knight was in his third season with Lamar and had two more seasons left on his contract.
"I was told last night to meet with the president and the AD this morning at 10 a.m.,'' Knight said. "I knew it. There's no talk. They said they want to go in a different direction. We struggled for two years. It's all based on the record. It's part of the business.''
