The former coach died in his sleep, his agent, Pete Roussel, said.

Dimel earned All-American honors during his stint as an offensive lineman at Kansas State before he made the leap to coaching. After serving in a variety of assistant roles under Kansas State coach Bill Snyder, Dimel was named the Wildcats' offensive coordinator ahead of the 1995 season.

Dimel returned to Kansas State in 2009 and regained his offensive coordinator title. His second stint with the Wildcats ended in 2017, but his complete tenure spanned 20 seasons. During that time, Dimel was part of a staff that coached in 12 bowl games and won the Big 12 championship in 2012.

Snyder released a statement Tuesday.

"Obviously, we are very saddened by the passing of Dana," Snyder said in a statement. "He was a special friend and coaching companion. I admired his passion for helping his players and fellow coaches. He was a big part of the development of the Kansas State football program, and, along with his wife Julie, very meaningful in the Manhattan community."
