Pittsburgh Penguins goalie Matt Murray is week to week with a lower-body injury. Murray was placed on injured reserve Tuesday after leaving a 5-4 overtime win against the Philadelphia Flyers on Monday with 4:21 remaining in the second period. He had to be helped off rhe ice after Flyers forward Jakub Voracek crashed into him following a breakaway. "Injuries are a part of the game," Penguins coach Mike Sullivan said Tuesday. "Matt's a young guy (23). He's only going to get stronger and he's only going to get more durable with each game that he plays." Murray is 11-7-1 with a 2.95 goals-against average and .906 save percentage in 21 games (20 starts) this season. Tristan Jarry, 22, made eight saves on 10 shots in relief of Murray. He has stopped 41 of 45 shots in two straight wins after beginning his NHL career 0-1-2. Pittsburgh selected Jarry in the second round (No. 44) of the 2013 NHL Draft, one year after they drafted Murray in the third round (No. 83). Jarry said Murray has provided advice.
