DENVER - Colorado Avalanche left wing Steve Konowalchuk will have season-ending surgery on his right wrist, the team announced Sunday. The 14-year veteran tore ligaments in his wrist in a Nov. 21 game against Calgary. Avalanche athletic trainer Matt Sokolowski said in a release that he expected Konowalchuk to need six to seven months to recover. Konowalchuk scored six goals with nine assists and was plus-5 in 21 games this season. But what the Avalanche will miss most is his hustle, scrappiness and leadership. “He’s got one gear, and that’s all out,” Avalanche forward Ian Laperriere said. “Sometimes people don’t notice the dirty work he does in the corner, but that’s what he brings to the team. . . . Playing against him, I knew he was a hard worker. But playing with him, he’s one of the hardest working players I’ve played with in my career.” Turgeon out Forward Pierre Turgeon, who left Friday’s game against Columbus with a groin injury, sat out Sunday’s game and might not travel with Colorado on the upcoming two-game road trip. “He’s probably out for at least a couple days, and he’s questionable-doubtful for the trip,” Avalanche coach Joel Quenneville said after Sunday morning’s skate. Heading into Sunday’s game, Turgeon was leading the Avalanche in points with 25 (8 goals, 17 assists). Richardson makes debut Brad Richardson had just woken up from his pregame nap Saturday afternoon when he got the news. The 20-yearold center had been called up to the Avalanche from Lowell of the American Hockey League. “I was pretty happy, obviously, so I packed my bags and got ready to go,” Richardson said. Richardson, who had three goals and 10 assists in 17 games with Lowell this year, made his NHL debut Sunday night.
