Forward Reilly Smith scored his second goal of the game with 0.4 seconds left in the third period to get the Vegas Golden Knights back in their series against the Edmonton Oilers.

The wild finish in Saturday’s 4-3 win added to an already dramatic game in which Golden Knights captain Mark Stone left with an injury, injured teammate Brayden McNabb was a surprise participant and Oilers goalie Stuart Skinner started because of an injury to red-hot Calvin Pickard.

Oilers captain Connor McDavid had tied the score with about three minutes left, and the game looked like it was heading to overtime.

But in another defensive breakdown by the Oilers, William Karlsson carried the puck into the zone and fed Smith. He faked a shot, causing Edmonton defenders to drop to the ice in an attempt to make a block. He skated around them and Skinner and put the puck toward the net. It went in off Leon Draisaitl’s stick and out quickly.

An on-ice official waved it off, but officials conferred and said the puck went in. A review confirmed Smith beat the clock.

“I think from my angle, it looked like it hit the middle bar but it came out so fast and I wasn’t really sure if the time expired,” Smith told TNT. “And I take a peek at the ref and he’s telling me it didn’t go in. We were just fortunate we were able to get something with time running down there.”

The Golden Knights fell behind 2-0 and were able to rally without Stone, who left the game with about six minutes left in the first period. The team said he has an upper-body injury.

Skinner got the start because Pickard is day-to-day with an undisclosed injury. It was Skinner’s first start since he was pulled in Game 2 of the first round, leaving him at the time with a 6.11 goals-against average and .810 save percentage.

He stopped 20 of 24 shots, but was victimized by Oilers defensive breakdowns, including a bad line change that led to Karlsson’s goal that gave Vegas a 3-2 lead.

Edmonton’s six-game winning streak, all with Pickard in net, came to an end. The Oilers still lead the series 2-1 with Game 4 Monday night in Edmonton.

Highlights from Game 3 between the Golden Knights and Oilers:

“He obviously didn’t return, we saw that, but it doesn’t preclude him from playing the next game. We’ll know more (Sunday),” Cassidy said.

Smith, an original Golden Knight who was reacquired at the trade deadline, was one of the players who received more ice time in Stone’s absence.

“We’d like to have Mark back, obviously,” Cassidy said. “Hopefully, it’s nothing serious. He’s a big part of our team, but guys got to know we got to dig in.”
