Bowling Green coach Scot Loeffler, who also calls the plays for the Falcons, was ejected in the third quarter of Saturday's 56-44 victory against Buffalo after two unsportsmanlike penalties on back-to-back drives.
He became the first head coach ejected since a rules change in 2016.
"It's a great learning experience for every single person that was involved," Loeffler said. "I've got to do things better, but I also know exactly what was said and exactly what was done. As the leader and all that I've got to be better, but it's a great learning experience for every single party involved here."
Bowling Green associate head coach Steve Morrison, who also coaches the linebackers, took over the head-coaching duties on the field. Offensive coordinator and running backs coach Terry Malone has assumed play-calling duties from the booth, according to a school spokesperson.
Bowling Green, which was 0-4 in the Mid-American Conference, had a 28-23 lead over Buffalo when Loeffler was ejected.
In 18 minutes after Loeffler's ejection, Bowling Green scored more points than in any full game over the last two seasons.
The first penalty was called on Loeffler in the middle of a defensive drive, and the second occurred during a timeout after a Buffalo touchdown.
