Grubauer, called up early Wednesday to play in place of an ill Michal Neuvirth, replaced Braden Holtby in the second period of Wednesday's 4-1 loss to the Philadelphia Flyers, stopping all 14 shots he faced.

GREENBURGH, N.Y. -- Reinforcements are coming for the slumping New York Rangers.
Defenseman Ryan McDonagh declared himself healthy and ready to return to the lineup Thursday night against the Tampa Bay Lightning. Right wing Rick Nash continued to sound optimistic about his status while still saying he won't know for sure if he'll be able to play for the first time in five games until he gets to Madison Square Garden.
Defenseman Michael Del Zotto (lower-body injury) also skated in a regular green practice jersey Thursday morning at the team's suburban training facility, but he left the dressing room before the media could speak to him.
McGrattan was assigned to the Flames' American Hockey League affiliate in Abbotsford.

PHILADELPHIA -- If Michal Neuvirth were healthy, he'd be starting in goal for the Washington Capitals in their NBCSN Wednesday Night Rivalry game against the Philadelphia Flyers at Wells Fargo Center.
"It would have been a good night to give Neuvy a start," Capitals coach Adam Oates said prior to the game.
Coach Alain Vigneault said a CT scan taken on Wednesday morning revealed the fracture. He did not have a timeline for the return of his Selke Trophy-winning center, but it's bad timing for a team about to play 16 games in March.
"Any fracture is usually four to six weeks, depending on the nature of the fracture," Vigneault said. "Some are less -- hairline fractures. I haven't gotten at length with our doctors how long this will be."
Malkin skated for 30 minutes and reported no symptoms, according to the Penguins. There is no timetable for his return.
