UPDATE: TCU assistant athletic director Mark Cohen confirmed the firing in an email Monday morning. Athletic director Chris Del Conte said that while Johnson was a man of “unbelievable integrity,” the Frogs “simply did not have the success [they] envisioned.”

TCU has parted ways with men’s basketball head coach Trent Johnson after a four-year stint with the program, multiple sources reported late Sunday night.

The firing comes on the heels of a season in which the Horned Frogs finished 12-21 (2-16 in Big 12), a downgrade from the 2014-15 campaign.

Johnson was 49-74 at TCU, with a 8-60 Big 12 record.

Johnson came to TCU from LSU before the 2012-13 season. Arguably his biggest success with the Frogs came in his first year in Fort Worth, when TCU upset the No. 5 ranked Kansas Jayhawks in the former Daniel-Meyer Coliseum.

The next year saw TCU go winless in the Big 12 and just 9-22 overall, although the arrival of four-star center Karviar Shepherd gave fans hope that Johnson could bring TCU to national prominence.

In 2014-15, playing in a high school gymnasium while the Ed & Rae Schollmaier Arena was under construction, Johnson led the Frogs to an undefeated record in non-conference play.

The 13-0 Frogs cracked the national rankings in December 2014 when they appeared at No. 25 in the AP poll, but they couldn’t maintain the momentum, and won just 4 games in conference play.

Those 4 games were the most Johnson ever won in-conference as TCU’s head coach.

TCU is expected to announce the firing officially on Monday.

Correction: an earlier version of this story incorrectly gave the ranking of Kansas in 2013 as No. 1.
