Butler (lower-body) will play after being listed as doubtful.
Butler took part in the Flames' morning skate and will be in the lineup tonight in Edmonton. Butler has 10 points (2G / 8A) with a minus-17 rating in 59 games this season. Butler has been a big minutes eater for the Flames this season, averaging 19:48 TOI per game.
The Calgary Flames have officially traded defenceman Robyn Regehr to the Buffalo Sabres along with Ales Kotalik and a 2012 second round draft pick in exchange for defenceman Chris Butler and forward Paul Byron. The deal included all the particulars we had heard last night, with the only difference being the second round pick heading Buffalo's way instead of vice versa.
