Kreider was a healthy scratch for the Rangers’ 2-1 road loss to the Philadelphia Flyers on Thursday night, but was absent from the team’s practice Saturday morning with the injury. Tortorella said Kreider suffered in the injury during his time with Connecticut of the American Hockey League.
"I don’t know exactly what it is,' Tortorella said. "But it's not a serious injury. He'll get a couple days rest and we’ll see what happens from there."
The Rangers face the Toronto Maple Leafs on Saturday night and are scheduled to face the Flyers at home on Tuesday night.
