EDMONTON, Alberta — NHL official Chris Rooney was back on the ice Tuesday night for Game 4 of the Western Conference finals between the Edmonton Oilers and Dallas Stars.

It was the veteran referee’s conference finals debut, and a fitting return for Rooney given the circumstances. It was Rooney’s first game since he took a high stick to the face on May 17 during Game 7 of the Eastern Conference second-round series between the Toronto Maple Leafs and Florida Panthers.

Rooney was injured 13 seconds into the second period when Panthers’ defenseman Niko Mikkola caught him with the end of his stick while fighting for a puck. Rooney fell to the ice and was tended to by trainers from both teams.

While bloodied, he was able to leave under his own power. Rooney sustained a black eye and received stitches for his injury but had no lasting damage. He was replaced at the time by Garrett Rank, in the building on standby in case on injury.

It was clear even the day after his injury that Rooney, 50, hoped to resume duties at some point in the playoffs. The Boston native was finally able to step in for Game 4 with fellow referee Dan O’Rourke.

The pair was joined by linesmen Ryan Gibbons and Matt MacPherson. Referee Graham Skilliter and linesman Ryan Daisy were in the building as alternates.
