Backup Jacob Markstrom will get a chance to bounce back quickly from a 7-2 loss to the New York Rangers on Tuesday with an unexpected start because Ryan Miller has the flu and won't play. "It's good for him he's getting a chance right away," coach Willie Desjardins said of Markstrom, who made 18 saves on 25 shots against New York. "That's one thing about [Markstrom's] career, when he was in Utica [of the American Hockey League] he seemed to always bounce back with a good game, so it's a chance for him to do that." The Canucks called up Michael Garteig from Alaska of the ECHL to back up Markstrom after practice on Wednesday. "Ryan felt better today, but we didn't know how he'd feel through the night so we already called Garteig up, and he'll back up tonight," Desjardins said. Vancouver, which has two wins in its past 13 games, won't make any other lineup changes but will try to tighten up defensively; the Canucks have given up 27 goals in their past six games. "Our shots-against per game has been pretty good, but the chances we are given up are just too Grade A," Brandon Sutter said. "We have a defensive lapse and don't pick a guy up or leave a guy open, and it's almost a breakaway in front, so we just have to try to clean that up."
