The Vegas Golden Knights forward was disciplined for roughing/unsportsmanlike conduct against Colorado Avalanche defenseman Ryan Graves in Game 1 of the Stanley Cup Second Round at Ball Arena in Denver on Sunday.
The incident occurred at 8:04 of the third period. Reaves received two minor penalties for roughing and a match penalty. Graves played two more shifts, beginning at 16:13 and 18:16, and finished the game.
"I don't think you can call that physicality, to be honest with you," Avalanche captain Gabriel Landeskog said after the game. "Reaves is on a mission to hurt somebody in the third, and that's what he goes out and does."
Reaves will not be eligible starting in Game 2 of the best-of-7 series at Colorado on Wednesday (10 p.m. ET; NBCSN, CBC, SN, TVAS). The Avalanche won Game 1, 7-1.
Graves was called for interference for a hit against Golden Knights forward Mattias Janmark at 8:26 of the second period.
"I think emotions get away," Vegas coach Peter DeBoer said. "I think obviously the Graves hit on Janmark and Janmark leaving with the injury, you know, that's tough to watch, a defenseless player and one of your teammates getting hit like that. You know, it's hard not to carry that emotion through the rest of the game."
Janmark did not return to Game 1. DeBoer did not have an update Monday.
Janmark scored a hat trick for Vegas in a 6-2 win against the Minnesota Wild in Game 7 of the first round Friday. Acquired in a trade with the Chicago Blackhawks on April 12, he has scored six points (three goals, three assists) in eight games in the 2021 Stanley Cup Playoffs.
Reaves was suspended one game during the 2020 playoffs for an illegal check to the head against Vancouver Canucks forward Tyler Motte in Game 7 of the Western Conference Second Round. He was suspended three games during the 2015-16 season, when he played for the St. Louis Blues, for boarding San Jose Sharks defenseman Matt Tennyson on Feb. 22, 2016.
