The Vancouver Canucks will have to bounce back from their first regulation loss of the season without top-pair defenseman Chris Tanev, who is day to day with a lower-body injury. Tanev, who finished a 4-2 loss against the Anaheim Ducks on Sunday, will be replaced by 5-foot-10 rookie Troy Stetcher, a 22-year-old signed as an undrafted college free agent during the summer. Stetcher was called up from Utica of the American Hockey League even though the Canucks already had two spare defensemen. He will take Tanev's spot with Alexander Edler on the top pairing. "You always have to have guys that match up," coach Willie Desjardins said. "He played with Edler [in preseason]." Stetcher, who grew up nearby cheering for the Canucks, hopes being reunited with Edler will help settle his nerves in his first NHL game. "Pretty nervous right now to be honest and going to be excited when it comes," said Stetcher, who had one goal and two assists in four preseason games. "First NHL game, as a little kid grew up wanting to play for the Canucks and now the opportunity is here so want to make the most of it." Vancouver also called up forward Jayson Megna from Utica after Derek Dorsett was hurt Sunday and Alexandre Burrows was injured during a 4-3 shootout loss against the Los Angeles Kings on Saturday.
