Later in the broadcast, the team announced that he was ruled out with a knee injury and would not return to the game. The 49ers provided no further medical details at the time.
How the play unfolded: a short timeline
- Early in the series, Juszczyk took a handoff and was hit while changing direction.
- He spun and landed on his back, remaining on the field as medics evaluated him.
- After initial treatment, trainers helped him off the field.
- The broadcast later confirmed he would not be coming back due to a knee problem.
Immediate effect on the 49ers roster and game plan
The loss of Juszczyk removes a key blocking and short-yardage option for San Francisco. Coaches will need to adjust personnel for lead-blocking snaps and special teams roles.

Expect the team to monitor his condition closely and provide updates after imaging and evaluations. For now, the designation is limited to the in-game ruling.
Past off-field headlines: the “celebration” fine that drew attention
The injury arrives weeks after a separate controversy involving Juszczyk. The NFL fined him for a celebration staged after a touchdown during the 49ers’ game against Miami.
League officials cited standards of conduct and issued a $14,926 fine. Juszczyk insisted the gesture referenced his nickname rather than alcohol consumption.
Player response and appeal
Juszczyk has publicly disputed the characterization of the celebration. He appealed the fine and told reporters he normally celebrates by pretending to drink “juice,” a nod to his nickname, which teammates and fans often chant.
Teammates and peers weighed in
- George Kittle took the moment lightly and teased Juszczyk by giving him a new joke nickname during team meetings.
- Former Eagles center Jason Kelce urged Juszczyk to push back against the penalty, arguing the league could not prove the player was drinking beer.
What fans and analysts are watching now
With Juszczyk sidelined for the remainder of the game, analysts will track how the 49ers adjust short-yardage packages. Fantasy owners and bettors may also re-evaluate matchups depending on his official injury update.
The team typically releases more detailed medical news after tests. Fans should watch official 49ers channels and league reports for the next update on his knee.
Key takeaways and next steps for the 49ers
- Immediate status: Out for the game with a knee injury.
- Short-term impact: Coaching staff must reshuffle blocking and special teams roles.
- Follow-up: Expect imaging and a formal injury report from the team in the days ahead.
