However, last night it was Kassian who added the scoring touch to a 4-2 Vancouver victory.
Kassian assisted on all for Canucks goals while the Sabres managed just 18 shots - none by Cody Hodgson - for their eighth loss in nine games.
Buffalo got out to a quick start thanks to, who else, Tyler Ennis, who scored in the first 80 seconds on a nice wrist shot past Eddie Lack. Jamie McBain added to the lead two minutes later, finishing off a nice break-out play with his fourth of the season.
However, before the period was over, the Canucks would tie things up on goals by Brad Richardson and Shawn Matthias. But the second period would ultimately doom the Sabres - Nathan Lieuwen misplayed a long wrist shot from Canucks defenseman Yannick Weber and let in on of the softest goals of the Sabres season.
Buffalo wouldn't recover, or score again, losing once again and remaining 11 points behind the 29th ranked Oilers.
