Kevin Westgarth is a Princeton graduate who throws punches for a living. You might think he’s crazy. The Calgary Flames right-winger is also smart enough to understand the risks that come with being a member of the NHL’s fighting fraternity. “We’re doing it ourselves. We’re not children. We’re not unknowing combatants in this ring,” Westgarth said Tuesday at the Saddledome. “We’re completely aware of what can happen, what — at one point or another — will happen.” For Westgarth, it happened Saturday night at Rexall Place in Edmonton, when he crumpled to the ice after a right hook by Oilers enforcer Luke Gazdic in a consensual first-period fight and wobbled on his skates as he was helped back to the locker room. While his Flames teammates continued on to Minnesota to wrap up their two-game road-trip with Monday’s 3-2 loss to the Wild, the 30-year-old tough guy caught a ride back from Edmonton with his wife, Meagan, who was visiting friends in the provincial capital. “For years, regardless of how the fights have gone, she hates watching me do that, watching me fight,” Westgarth said. “It’s obviously something I’ve been doing for a while. It’s one of the things that has gotten me to where I am and I take a tremendous amount of pride in it. It’s not nice for her or my mother, for that matter, but I’ve been pretty good to them over the years without having something like that happen.
