49ers Eject Dre Greenlaw After Seahawks Sideline Altercation

A sideline confrontation involving San Francisco 49ers linebacker Dre Greenlaw and Seattle Seahawks players resulted in Greenlaw's ejection during Sunday's game at Lumen Field on October 11, 2026. The incident began when Greenlaw hit quarterback Sam Darnold as he ran out of bounds in the second quarter, then escalated into a headbutt against Seattle linebacker Ernest Jones, leaving Greenlaw facing possible additional NFL discipline.

According to coverage by Fox News, officials penalized Greenlaw for a personal foul after the contact with Darnold occurred along the Seahawks' sideline and extended into the bench area. Seattle players subsequently surrounded Greenlaw, and Jones confronted the San Francisco linebacker.

Greenlaw was still wearing his helmet, while Jones was not. Greenlaw then struck Jones with a headbutt. Television footage showed Jones wiping his face with a towel, apparently tending to a cut, before officials ejected Greenlaw from the contest.

The ejection does not automatically establish whether Greenlaw will receive a suspension. According to NFL disciplinary guidelines described by Fox News, the league reviews incidents after games and may issue a warning, fine or suspension based on the severity of the conduct and the circumstances involved.

The league's disciplinary framework allows additional punishment when conduct constitutes a serious violation of player safety or conduct detrimental to the League. Any further sanction would follow a separate review rather than result automatically from the ejection.

Greenlaw has previously faced league discipline. During the 2025 season, while playing for the Denver Broncos, he was suspended after chasing and verbally threatening referee Brad Allen following a 33-32 victory over the New York Giants in Week 7. The league determined that his behavior violated rules prohibiting abusive, threatening or insulting language and gestures toward game officials.

Fox News also reported that Greenlaw received an $11,941 fine the week before the Seattle game for unsportsmanlike conduct after taunting the Broncos' sideline and head coach Sean Payton. In 2023, he was ejected following a sideline altercation with Philadelphia Eagles head of security Dom DiSandro.

The confrontation comes during Greenlaw's return to San Francisco after spending the 2025 season in Denver. According to USA Today’s Niners Wire, injuries limited his time with the Broncos, where he recorded 43 combined tackles, one sack and one interception in eight games before his departure.

Greenlaw returned to the 49ers on a one-year contract in 2026, joining wide receiver Deebo Samuel in a reunion with head coach Kyle Shanahan. Both players had spent their first six NFL seasons in San Francisco after being selected in the 2019 draft.

Shanahan explained the personal connection behind the team's decision to bring back former players in an interview with NBC Sports Bay Area's Matt Maiocco, as reported by Niners Wire and Yahoo Sports.

"It was their home," Shanahan said of the returning players. "It's where they started out. They went other places. Whatever happened there doesn't really matter, but I think that they were excited to come back and I know how excited we were to get them back."

Shanahan also said his assessment of Samuel's performance in Washington influenced the decision to reunite with the receiver. Reviewing game footage helped the coaching staff determine that Samuel retained the abilities that had made him productive in San Francisco.

"I thought he was going to end up somewhere else, but we did watch him on tape, and when you put the tape together, you see Deebo. You could see in Washington that he still had the same skill set ... we thought on tape last year, we didn't see a guy who had changed. It looked like the Deebo we had always known."

Yahoo Sports also reported Shanahan's broader explanation of what makes Greenlaw and Samuel valuable to the team, emphasizing their physical playing styles and contributions on opposite sides of the ball.

"I mean, it starts with the types of players they are. Deebo and Greenlaw, you can almost talk like the same guy, like they both have that effect, Niners fans would agree."

Shanahan described Samuel's physical running and playmaking ability before comparing the receiver's impact on offense with Greenlaw's defensive style.

"The mentality that we've had on offense with Deebo out there, how physically he runs with the ball, the way he runs people over, the plays he can make, and then I would say Greenlaw is almost his equivalent on defense. The way he runs around and hits people, how violent he is, all the plays he's made for us, big-time plays to get us in the playoffs."

Greenlaw's early-season production had supported San Francisco's decision to bring him back. Sports Illustrated reported that he recorded 34 total tackles and 16 solo tackles through the first four games of the season, along with one forced fumble. He also registered a game-high 12 tackles against his former team, Denver.

His return followed a difficult year with the Broncos, where a significant quadriceps injury delayed his season until Week 7 and a subsequent hamstring problem ended his regular season. His latest ejection now leaves the NFL to determine whether the incident against Seattle warrants additional punishment.
