What happened: Colorado Avalanche defenseman Cale Makar headed to the locker room after a collision with Mats Zuccarello, per SportsCenter. Makar was quick off the ice and down the tunnel following the contact, with reports describing an apparent upper-body injury. His return status was not immediately clear at the time of the signal.

Why it matters: Makar is the engine of Colorado's blue line and one of the league's most impactful two-way defensemen, so any extended absence reshapes the Avalanche's outlook. Colorado has already clinched a playoff berth, making his health the dominant storyline rather than seeding. A serious injury would swing series odds and individual prop markets tied to Colorado's defense.

What to watch: Watch for an official team update on Makar's status, including imaging results and a return-to-play timeline. Any confirmation of an upper-body issue or missed time will move Avalanche series prices.
