Crosby, the captain of the Penguins and the reigning Conn Smythe Trophy winner, missed the first six games of the season due to a concussion. He was injured during practice following the World Cup of Hockey where he led Canada to a championship. Given how much time he missed a few years ago with a concussion only missing six games a positive development for both him and the Penguins.
Murray, who took over the starting job in the playoffs last year when Fleury was sidelined at the start of the first round, was injured at the World Cup while playing for Team North America and has been sidelined since.
Even with the return of Crosby and Murray on Tuesday the Penguins are still missing a pretty significant player as defenseman Kris Letang remains sidelined with an upper body injury.
