Anaheim Ducks forward Trevor Zegras suffered a lower-body injury in the second period of Wednesday's 4-1 loss to the Vegas Golden Knights and did not return.
Zegras took an awkward fall and had to be helped off the ice by his teammates.
The 23-year-old has recorded four goals and six assists in 24 games this season.
Zegras was the Calder Trophy runner-up in 2022 after the first of back-to-back 60-point seasons. However, he's since battled injuries and failed to replicate that success.
