NHL admits to error on offsides call

The NHL might just have handed the Rangers a win they didn’t deserve.

The Post’s Larry Brooks confirmed via a league source that the NHL admitted to both the Rangers and Sabres it got an offside call wrong that disallowed Buffalo’s game-tying goal with 56.2 seconds to go on Friday night. Though the play looked to be clearly offside, the league said it couldn’t definitively determine whether Victor Olofsson, who had the puck along the boards, had possession or not before Rasmus Dahlin touched up. The Athletic first reported the error.

In a statement, NHL senior executive vice president Colin Campbell said the goal should have stood because “in instances when video replay cannot definitively determine a play, League policy is to stay with the original call on the ice.”

On the play, Dahlin was clearly over the blue line as Tage Thompson passed it to Olofsson just on the other side of the line. Dahlin went to touch up as Olofsson entered the zone, but the league said it’s not clear that Olofsson had possession before Dahlin got to the blue line. Thompson also was very nearly over the line before Olofsson’s skates crossed over.

After the game, which the Rangers won 2-1, head coach Gerard Gallant said the team knew “right away” that the call would be overturned.

“As soon as they entered the zone, the video guys said [it was offside],” Gallant told reporters. “So you weren’t really feeling the pressure when they did score, because we knew.”

Added Mika Zibanejad: “We knew it pretty early. Came back to the bench and checked the offside earlier than it came back. So we knew. And when you get a chance like that, you get a second chance, you just gotta make sure you stop the puck from going in again.”

Sabres coach Don Granato told reporters that he asked the officials to review whether Dahlin touched up, “but the league made a decision.”

“They’ve got camera angles, and they’re on it,” Granato said. “That was my question to the officials, and you move on.”

Time was added back on to reflect when the non-infraction occurred, but the Rangers stonewalled Buffalo for the final 90 seconds to move to 18-5-3 and first place in the Metropolitan Division.

➤ The Rangers have scored on the power play in eight of their last nine games following Zibanejad’s first-period tally on Friday. At 24.68 percent, the Rangers are seventh in the league in conversion rate on the power play.

After successfully killing two penalties against the Sabres, the Blueshirts rank seventh on the penalty kill, at 83.54 percent.

➤ The Rangers will finish their season series against the Predators on Sunday night at the Garden. In October, they won 3-1 at Nashville on a go-ahead goal from
