The Calgary Flames are learning their lessons in truculence at training camp.

In a rare sight for an NHL club, the team devoted part of Thursday's practice to fighting technique, showing several players from their group of non-regulars how to drop the gloves.

"We're teaching the young players how to defend themselves," head coach Bob Hartley explained after practice.

The players - which included centres Paul Byron and Corbin Knight, right winger Ben Hanowski and left winger Trevor Gillies - were being taught on the ice by an outside instructor.

The Flames' regular roster already includes enforcers like wingers Brian McGrattan and Brandon Bollig and defenceman Deryk Engelland who signed a three-year, $8.7 million contract over the summer.
