Moose defenceman Nicholas Jones, who assisted on the lone Moose goal on the afternoon was succint in his assessment of the loss.
"We've seen it all year in back-to-backs you know where we go out there and feel like the front end of the back-to-back we've played really well and you know they're going to be desperate on the second game. And we didn't match that intensity from the opening puck drop," he said.
Manitoba travels to Rockford for a Saturday matchup while the Icehogs travel to Chicago for a Tuesday game against the Wolves.
