The Flames acquired McGrattan a day earlier from the Nashville Predators in exchange for Joe Piskula. McGrattan has played two games with the Predators and six games with the Milwaukee Admirals (American Hockey League) this season.
This will be McGrattan's second time suiting up for the Flames after playing for Calgary during the 2009-10 season when he had one goal and three assists along with 86 penalty minutes in 34 games and was a plus-3.
Aliu played two games for the Flames on his call-up and registered 10 penalty minutes.
If you want to prove people wrong, you've just got to go out and do it. Yeah, we blew 3-2 series leads the last two years, but no one is going remember that if we go out there on Saturday night and beat these guys and go play in the Stanley Cup Final. We need to get back to work and we'll start to do that tomorrow.
