Red Wings forward Valtteri Filppula finished his preliminary preparation for the world championship in fine fashion Monday, using four points to lead his Finns to victory. The Swedes, meanwhile, look like they will regain the services of defenseman Jonathan Ericsson. Last week, after Ericsson suffered a back injury in the first game of the tournament, the Wings were under the impression Ericsson wouldn't play again. But he has apparently improved enough that he went on the ice Monday, and he told Sweden's Aftonbladet that he hopes to play in the quarterfinals, which begin Thursday.
