Defenseman Andrej Sekera was not at practice Saturday and Canes coach Kirk Muller said he is very doubtful for Sunday's game against the Vancouver Canucks. Sekera has an undisclosed upper-body injury and did not play Friday in the Canes' 5-2 loss to the New Jersey Devils. His absence caused some shuffling on the back end, with Ron Hainsey taking Sekera's spot in the No. 1 pairing with Justin Faulk and Mike Komisarek playing with Brett Bellemore. Sekera was missed, both defensively and on the power play. He also has been productive offensively, with three goals and two assists in his last five games before Friday. "Let's not kid ourselves, he was playing really good hockey," Muller said. "He was eating up minutes. He was on the power play, killing penalties, playing against the top guys. "Mike (Komisarek) stepped in and played really well for not playing in a while. He played hard. But it does change your dynamics. (Bellemore) has to move over to the left side for the most part. The power-play units change. But at the end of the day you have to find a way to get it done." The Canes led the Devils 2-1 after two periods Friday, but allowed three goals in a five-minute span than began about nine minutes into the third. Jaromir Jagr's 692nd career goal finished off a four-goal period for New Jersey. The Canucks had a Saturday afternoon game in New York against the Rangers, in coach John Tortorella's return to Madison Square Garden. Tortorella was fired by the Rangers after last season.
