Minnesota center Mikko Koivu stayed behind as the Wild left for a five-game road trip to continue rehabilitating a broken bone in his left leg. Koivu was injured on Nov. 17 when Vancouver defenseman Mattias Ohlund hit him in the leg with a two-handed swing of his stick that earned Ohlund a suspension. Koivu has resumed skating, but the team said Thursday that he was not yet ready for full practice and will stay home for the first two games of the trip. The Wild play at Detroit on Friday and at Columbus on Saturday before heading West for a three-game California swing that starts in San Jose on Tuesday. Koivu is expected to join the team in San Jose. Team doctors initially said Koivu would miss only about a week, but in a statement released by Thursday, the Wild said the prolonged absence can be explained because "bodies heal on their own schedule, and there is nothing we can do to hurry it up."
