PITTSBURGH -- Already missing franchise defenseman Kris Letang, the Penguins' defense of the Stanley Cup got a little harder Wednesday night. Starting goalie Matt Murray was a late scratch after exiting warm-ups early, giving longtime Penguins goalie Marc-Andre Fleury the surprise start.

Fleury came up big as he made 31 saves in a 3-1 victory that gave the Penguins a 1-0 series lead over the Columbus Blue Jackets.

After Wednesday's game, Sullivan said Murray suffered a lower-body injury during warm-ups and will be re-evaluated Thursday. Murray was not on the ice for Thursday's practice.

Murray led Pittsburgh to a Stanley Cup last spring and had been declared Wednesday night's starter by coach Mike Sullivan following the morning skate.

Fleury's promotion and Murray's inability to even dress for the game forced 21-year-old Tristan Jarry into the backup role. He has one game of NHL experience.

Fleury was 18-10-7 this season for the Penguins with a .909 save percentage. He started one playoff game during the Penguins' run last spring. He has a 53-45 career record with a .906 save percentage in the postseason.
