Oregon quarterback Dante Moore suffered a severe head injury on a late hit by Southern California linebacker Desman Stephens II during the second quarter of their Sept. 26, 2026, Big Ten matchup in Los Angeles, sparking on-field chaos, a player’s ejection, and widespread criticism over subsequent sideline celebrations.
Saturday night’s clash at the Los Angeles Memorial Coliseum between the No. 20 Oregon Ducks and the 12th-ranked USC Trojans quickly turned from a marquee Big Ten battle into a flashpoint for player safety and sportsmanship. Early in the second quarter, Moore scrambled deep into USC territory, sliding to complete an 11-yard run to the Trojans’ 12-yard line. As Moore slid, Stephens delivered a vicious forearm blow directly to the quarterback’s head and chest. Moore’s head snapped back violently against the turf, leaving him motionless on the grass as support staff rushed to his aid.
The violent collision immediately boiled over onto the turf. Oregon players rushed to confront Stephens, triggering a prolonged on-field melee that resulted in unsportsmanlike conduct penalties for both teams. The game was delayed for roughly 15 minutes as medical personnel cautiously treated Moore, placing him in a neck brace and strapping him to a stretcher before loading him onto a cart and into a waiting ambulance at the base of the Coliseum tunnel. Teammates gathered around the cart to offer support, and Moore was seen moving both of his hands as he was transferred to Los Angeles General Hospital.
Desman Stephens and the Sideline Backlash
While medical staff tended to the fallen Heisman Trophy candidate, attention quickly shifted to Stephens’ reaction. Instead of showing concern, the USC linebacker was caught on the NBC broadcast smiling, high-fiving teammates, and laughing as he made his way back to the sideline. Oregon coach Dan Lanning appeared visibly frustrated by the behavior while checking on his quarterback.
The backlash from analysts and broadcasters was swift. During the halftime show, members of the studio crew condemned the celebration as inappropriate.
I think some of the antics after the play are what people can and should be disappointed with.

“The fact that Desman Stephens II was over on the sidelines laughing, guys were coming over to him dapping him up, like saying ‘Good job,’ That was a bad look for USC.”

Stephens was assessed a targeting penalty and ejected from the game, heading immediately to the Trojans’ locker room. Yet the controversy deepened in the second half when Stephens returned to the USC sideline.
Lincoln Riley Defends Sideline Return Amid NCAA Rule Loophole
When questioned after the final whistle about why a disqualified player was permitted back on the field area, USC coach Lincoln Riley expressed confusion over the inquiry.
The situation exposed a peculiar loophole in collegiate rulebooks: while an ejected player must leave, NCAA regulations technically permit a disqualified player to remain on the sidelines. Critics argued that allowing Stephens to return added tone-deaf optics to an already alarming sequence of events.
NBC reporter Nicole Auerbach voiced support for formal league discipline, stating on the broadcast that she believed the Big Ten should look at the play and aftermath for possible punishment on Stephens.
Medical Update and Game Aftermath
Despite the severity of the collision, early updates from the hospital offered a measure of relief. Speaking to sideline reporter Kathryn Tappen during the broadcast, Dan Lanning confirmed that Moore had movement in all of his extremities. We’re getting him checked out. We have to be thorough with our evaluation,
Lanning said.
On the field, Dylan Raiola stepped in to replace Moore for the Ducks. Raiola made an immediate impact, throwing a touchdown pass to Evan Stewart on just his second snap to push Oregon ahead 10-7 in a game overshadowed by the frightening collision.
