New York Islanders defenseman Radek Martinek will be out of the lineup for four weeks due to a broken bone in his foot. Martinek, one of New York's top defensemen this season, was injured Tuesday night during the Islanders' victory over the Rangers. He finished that game and then played the following night in a loss at Ottawa. "Radek has been a warrior for us, maybe our most consistent defenceman," Islanders coach Ted Nolan said in a release Saturday. "It says a lot about him that he continued to play during the Rangers game and the whole game the next night in Ottawa because he didn't want to take himself out of the lineup. "But this is the right thing for him. As much as we'll miss Radek, and we know how much he hates being out, we look forward to getting Radek back at 100 per cent." The 30-year-old Martinek is in his fifth NHL season, all with the Islanders. He had two goals and 11 assists with a plus-15 rating, tops among the team's defencemen, while playing in New York's first 36 games.
