Ivanans' stats over the last two seasons: two games, minus-two, 19:20 total ice time, five penalty minutes.
Those five penalty minutes are extremely significant, however.
Ivananas fought Steve MacIntyre, then of the Edmonton Oilers (currently with Pittsburgh's AHL team), on the first night of the season.
MacIntyre knocked him out, causing Ivanans to miss the rest of the season with a concussion.
The Flames seem to be using Guillaume Desbiens as their NHL enforcer. He has four fights in eight games, two against notable heavyweights Matt Kassian of Minnesota and Paul Bissonnette of Phoenix.
At the AHL level, the Flames have been using Pierre-Luc Letourneau-Leblond; he's played in 42 games whereas Ivanans has appeared in 26.
Leblond battled Cam Janssen two seasons ago in one of the longest NHL fights of all time.
