Oregon football suspended its strength and conditioning for one month, following an incident which sent multiple players to a hospital with a dangerous condition. Head Coach Willie Taggart apologized Tuesday, saying that he held himself “responsible.”

Offensive linemen Doug Brenner and Sam Poutasi and tight end Cam McCormick were reported to be in fair condition by The Oregonian, with Poutasi’s mother telling the newspaper that he was diagnosed with rhabdomyolysis, a syndrome in which damaged skeletal muscle degenerates and leaks into the bloodstream. It can lead to kidney failure, but if victims are treated quickly, they often fully recover.

Irele Oderinde was handed the one-month ban, without pay, for his role in the incident. The Oregonian reported that Oderinde put players through a grueling workout, including “an hour of continuous push-ups and up-downs,” after which some players “complained of discolored urine.”

The university issued a report on the matter, including Taggart’s apology and a statement from the Ducks’ athletic director. Oregon said that, following the workout, “one student-athlete complained of muscle soreness and displayed other symptoms of potential exercise-related injury,” with two other players “identified with similar symptoms.”

“I have visited with the three young men involved in the incidents in the past few days and I have been in constant contact with their families, offering my sincere apologies,” Taggart said in a statement. “As the head football coach, I hold myself responsible for all of our football-related activities and the safety of our students must come first. I have addressed the issue with our strength and conditioning staff, and I fully support the actions taken today by the university. I want to thank our medical staff and doctors for caring for all of our young men, and I want to apologize to the university, our students, alumni and fans.”

Taggart was hired to coach the Ducks in December, coming over from South Florida after Oregon fired Mark Helfrich, who had led the football program for four seasons. Oderinde came over from South Florida, as well, after having played at Western Kentucky in the early 2000s while Taggart was an assistant coach there.

Oregon announced Tuesday that its strength and conditioning coach will no longer report to the head football coach but to the school’s director of performance and sports science. “All workouts moving forward have been modified,” Oregon said.

“The university holds the health, safety and well-being of all of our students in high regard,” the Ducks’ AD, Rob Mullens, said in a statement. “We are confident that these athletes will soon return to full health, and we will continue to support them and their families in their recoveries.”
