Following a season in which his unit proved to be UCF's strongest, defensive coordinator Tyson Summers is leaving UCF to run the defense at Colorado State, according to a report from ESPN's Brett McMurphy.

Since his hiring in 2012, Summers has been one of UCF's strongest coaches and recruiters. After coaching the linebackers for the 2012 and 2013 seasons, he took over as defensive coordinator on an interim basis for the Tostitos Fiesta Bowl.

Head coach George O'Leary hired Paul Ferraro to run the defense for the 2014 season, and Ferraro resigned before spring practices started. The resignation opened the door for Summers to take over as defensive coordinator.

The Knights finished the regular season in the top 10 in many key defensive categories including total defense, run defense, scoring defense and red zone defense.

Summers was a strong recruiter in Georgia, and also was instrumental in developing linebackers such as Terrance Plummer, who was named the team's MVP, and Troy Gray. Both Plummer and Gray will graduate this year.

O'Leary told the Orlando Sentinel that he would take his time in naming a replacement — his third defensive coordinator in 12 months.
