Ole Miss coach Lane Kiffin on Wednesday confirmed previous reports Trigg had left the team.
Trigg had played in 10 games since transferring from USC along with quarterback Jaxson Dart before last season. He caught 21 passes for 221 yards and four touchdowns at Ole Miss. That includes four catches for 65 yards and a touchdown in three games this season.
"We wish him nothing but the best," Kiffin said. "He's not part of our program."
Trigg's bio has been removed from the website of No. 20 Ole Miss.
