Tempers flared during the joint practice between the San Francisco 49ers and the Las Vegas Raiders, as intensity boiled over into a brief scuffle on the field. What began as a normal competitive drill quickly turned into a moment of chaos when players clashed in front of both coaching staffs and teammates.
Witnesses at the 49ers’ facility said the atmosphere was already heated, with both sides pushing each other hard to prove their worth. Then came the flashpoint: one Raiders rookie took things too far, shoving and throwing a strike at a 49ers rookie linebacker. That hit sparked an immediate response from San Francisco’s sideline.
The Raiders player involved was identified as rookie Marcus Holloway, while the 49ers rookie targeted in the incident was linebacker Curtis Jacobs. The altercation left teammates stunned, but it also sparked one of the most vocal reactions of the day.

49ers wide receiver Deebo Samuel didn’t hesitate. Charging in to defend his teammate, Samuel got in Holloway’s face and shouted: “You think you can take cheap shots at my guy? Not here. You mess with one of us, you mess with all of us.” His reaction quickly drew teammates from both sides, but staff members and coaches swiftly stepped in before it could escalate further.
After a few tense moments, order was restored, and the session continued. No punches were thrown after the initial contact, and practice wrapped up without further incident. Sources confirmed it was treated as a minor misunderstanding, with no disciplinary action handed down to either side.
Still, the scene highlighted the intensity of camp battles — where rookies fight for recognition, veterans protect their own, and emotions can boil over in an instant. For 49ers fans, Samuel’s willingness to defend his teammate sent a clear message: this locker room is united, and no one will stand by if a fellow Niner is disrespected.
