Patrick (upper body) left Wednesday's game versus the Avalanche in the first period, Jesse Granger of The Athletic reports.
Patrick got hit up high by Nathan MacKinnon, which sent the former crashing into the boards. Patrick didn't come back to the bench at the start of the second period. Given his history with concussions and migraines, it wouldn't be surprising to see the Golden Knights hold him out of the rest of the contest. The 23-year-old should be considered day-to-day ahead of Friday's game versus the Kings. If Patrick has to miss time, Keegan Kolesar would likely enter the lineup.
