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.

We will have a full write-up including cap implications and profiles of Butler and Byron later today.
