Despite securing a victory against the Utah Tech Trailblazers in Week 1, the BYU Cougars are in no mood for celebration. Running back Sione Moa sustained major structural damage in the first half of the game and was immediately ruled out for the remainder of the contest. In the days that followed, silence from both the program and the player left fans anxious about his condition. Now, the official medical diagnosis has been revealed, leaving his ultimate return timeline entirely undecided.

Moa instinctively knew something was severely wrong on the field, though he initially tried to fight through the mental panic. As he exited the turf, he desperately maintained his composure, hoping his worst fears were entirely irrational. Unfortunately, medical evaluations confirmed every athlete’s worst nightmare: a torn MCL, a torn PCL, and severe cartilage damage. In an emotional social media post, the junior running back shared a photo of himself wound up in a hospital bed to open up about the setback.

“On Saturday night I got rolled up on awkwardly during a tackle in the first quarter, tearing my MCL and PCL, while also finding cartilage damage in my knee. Same leg as before,” he wrote in an Instagram post. “My heart sunk. I got up from the ground, looked down and knew immediately what was happening. I jogged off the field reluctantly, hoping and praying i was being overdramatic. And then eventually reality caught up to me.”

The incident occurred with less than five minutes left in the opening quarter when an awkward tackle folded his right leg.

This devastating blow carries an extra layer of heartbreak considering Moa survived a life-threatening injury to that exact same limb last season. In 2025, during a brutal game against East Carolina, Moa took a violent hit that caused severe swelling and nerve damage, forcing doctors to perform an emergency fasciotomy. He was in genuine danger of losing a portion of his leg before persevering through a grueling ten-game recovery to make the 2026 roster. Reliving that trauma has taken a massive toll on his mental health.

“I would be lying if i said these past few days haven’t been my hardest days mentally,” Moa further added. “Working so hard to come back from something so exhausting, just to go back to square one. I felt like all of my happiness was stripped away from me.”

 While Moa battles through this personal trial, the Cougars must completely adjust their offensive strategy. Significant ligament tears requiring reconstructive surgery typically demand several months of rigorous physical therapy.

What Does The Cougars’ Depth Chart Look Like?

Head coach Kalani Sitake provided a slight glimmer of hope by noting that none of the team’s Week 1 injuries are officially considered season-ending. However, Moa will remain sidelined for a substantial portion of the regular season as he focuses on his rehabilitation. With the dynamic running back out of commission, his positional counterparts must immediately step up to fill the void. Preston Rex, Journee Tonga, and Devaughn Eka are all expected to shoulder increased workloads moving forward.

Rex currently slides into the running back rotation on the Cougars’ updated second-week chart, carrying heavy expectations from the coaching staff. On the defensive side of the ball, sophomore Tommy Prassas is stepping in to replace injured safety Raider Damuni alongside starter Faletau Satuala, while Nusu Taumoepeau anchors the fieldback position. BYU must quickly solidify these rotations as they prepare for their upcoming clash against the Arizona Wildcats.

The Wildcats are dealing with their own minor injury concerns, listing wide receiver Scotty Brennan and running back Cornelius Warren III as questionable, though neither serves as a primary starter. For BYU, however, losing a weapon of Moa’s caliber is a massive hurdle to clear. The program now faces the difficult task of adapting to his absence while rallying behind their resilient running back’s long-term recovery.
