It had been a long time coming for Derek Dorsett, who finally made his Rangers debut Saturday after having been sidelined with a broken clavicle he sustained playing for Columbus nearly a month before coming to the Blueshirts on April 3 as part of the package for Marian Gaborik.

“I felt a lot of emotions going in,” the jagged-edged winger said after playing 15:17 in his team’s Game 2, 1-0 overtime defeat to the Capitals. “I was up early in the morning.

“I was like a little kid at Christmas.”

Dorsett, who played primarily on a line with Derick Brassard and Taylor Pyatt, added grit and a down-low presence to the lineup.

The winger picked up an offensive zone high-sticking penalty at 15:58 of the first in a sparring match with Steve Oleksy that began moments earlier when Dorsett bumped the defenseman following an icing touch. He also was charged with diving at 5:28 of the second when he went down after drawing an interference penalty against Jason Ward.

“I have to be more disciplined. I can’t take an offensive-zone penalty,” Dorsett said. “I tested [the shoulder] one my first shift in a collision and it felt great.“I felt better as the game went on. I was more confident and more comfortable.”
