ALLEN, Texas -- A string of controversial calls led to coach Terry Ruskowski's ejection as the Quad-City Mallards fell 6-2 to the Allen Americans Sunday at the Allen Event Center.

Late in the first period, Jonathon Zion scored on the power play to give the Americans a 2-0 lead. The Mallards argued that Jonathan Lessard knocked over Mallards goaltender Thomas Heemskerk before the goal, but referee Jake Brenk declined to give a goaltender interference penalty and instead gave the Mallards bench a disputing the call minor penalty.

"You've got to make an effort to get off the goalie," Ruskowski said. "There was no effort to get off the goalie and a wide-open net, so I slammed the door because I was disgusted, so he gave me a penalty."

Matt Boyd later scored on a power play cut the Allen lead to 2-1 at the 3-minute, 43-second mark of the second period, but the Americans responded with four unanswered goals.

After Heemskerk was pulled for Ty Rimmer following Tyler Ludwig's goal that made it 4-1, Lessard and Jordan Lane got into a skirmish at 10:40. Lessard was only given a roughing penalty, while Lane was given a double minor and Ludwig scored on the man advantage which led to Ruskowski getting ejected with a game misconduct.

"After a really questionable call, I was clapping my hands and he kicked me out of the game, for clapping my hands," Ruskowski said, "Two guys were going at it. How do we get an extra two with two guys facing each other doing what they were doing? It's absolutely ridiculous."

Ty Rimmer made 14 saves in the relief effort while Heemskerk made just nine in the loss, which drops the Mallards — who began the day tied with Allen for fourth in the league standings — into sixth place.
