Mighty Mouse Mark Arcobello, who just signed his first one-way contract, is game for being a utility player here next season if it keeps him earning an NHL wage, within physical reason. “I can’t be like (Luke) Gazdic ... I’m not going to be a fighter,” the five-foot-eight, 166-pound Arcobello said jokingly Monday after the signing was announced. Maybe not, but Gazdic, the biggest, baddest player on the Edmonton Oilers roster, and Arcobello, the smallest, have one thing in common: Bad shoulders. Gazdic, who stands six-foot-four and 240 pounds and had 15 fights in his first NHL season, needs shoulder surgery. The Oilers aren’t saying what the injury is exactly, but it could be a torn labrum, which was suffered in recent times by the likes of Taylor Hall and Ryan Nugent-Hopkins. If that’s the case, he’ll probably be out of the lineup for six months, which means wouldn’t be ready for training camp come September. With just seven games left, the Oilers decided to get him into an operating theatre rather than wait until season’s end in mid-April. Gazdic will have surgery next week Arcobello, who had 28 points in 15 AHL games in Oklahoma City after spending the first four months here before he was sent down Feb. 1, hurt his shoulder against Grand Rapids March 15 when drilled into the boards. He’s likely out for the rest of the regular season, with the Barons are four points out of a playoff spot. If they make the playoffs, he might be ready for the understaffed Barons, who are now thin at centre with Arcobello hurt, Anton Lander with the Oilers and Will Acton just recalled to Edmonton because of the run of injuries to the NHL squad.
