Colorado State head coach Deion Mora removed Tyson Summers as defensive play-caller during the first half of a lopsided loss to Oregon State, later confirming Summers is no longer with the football program. The Rams, now 2-3, continue to struggle on defense, ranking near the bottom of the nation in scoring and yards allowed, while Oregon State dominated with 727 total yards.
Tyson Summers had been at Colorado State since 2025. However, that parting appeared to happen during the game and not after it.
Mora said that Summers was replaced as the team's defensive play caller during the first half of the blowout loss and "Tyson was relieved of his play-calling duties. He left the field and he is no longer with this football program," Mora said in his postgame media session, before following up with "that is a permanent.
"The loss dropped Colorado State to 2-3 and also further solidified the Rams' status as one of the worst defenses in the country. Entering Week 5, Colorado State ranked 129th out of 138 in scoring defense, allowing 34.2 points per game. And, somehow, the defense was letting up 7.4 yards a play. Oregon State had 727 yards of total offense on 71 plays Saturday.
QB Braden Atkinson was 30-of-34 passing for 413 yards and five TDs, while the Beavers rushed 36 times for 291 yards as a team. Summers and Mora were in their first year together after Mora was hired as Colorado State's coach at the end of the 2025 season. Summers was Colorado State's defensive coordinator in 2025 under Jay Norvell and was the team's interim coach after Norvell was fired midway through the season.
He came to CSU after numerous stops as a defensive assistant following a two-year tenure in charge of Georgia Southern in 2016 and 2017.
