Input: The Penguins appeared to tie it 2-2 on a Jake Guentzel shot at 11:33 but Quenneville successfully challenged that defenseman Olli Maatta interfered with  goalie Corey Crawford .
The Hawks had a couple of injury scares in the second period. Defenseman Connor Murphy exited briefly after blocking a shot  but the major concern came when Evgeni Malkin collided with  Crawford  in a chilling moment at 8:43. Malkin's thigh appeared to make contact with  Crawford 's head  sending  Crawford  backward onto the ice and Malkin to the penalty box for goaltender interference.
 Crawford  went back into the Hawks' locker room for further evaluation of a potential concussion. Quenneville said  Crawford  had  his  "bell rung a little bit there" but  Crawford  said  he  felt fine and the evaluation was more "precautionary" than anything.
 Crawford  wasn't out for long.  He  re-entered the game 2:52 later â and  he  returned in peak form.  He  finished with 35 saves  while saving  his  best for last. With less than 18 seconds remaining   he  stuck out a pad in the hope it would stop a Phil Kessel shot from going in an open net. With a little help from Brent Seabrook  who got a stick on it   Crawford  made the stop.
"I don't know how it stayed out  " Crawford  said.
2.  Corey Crawford   Blackhawks: Left briefly  but returned to make 35 saves.

After allowing shorthanded goal Blackhawks finish power play with winning score
