Vancouver Canucks center Filip Chytil may miss for the rest of the season after experiencing a setback in his attempt to return from another concussion. Coach Rick Tocchet said Tuesday that Chytil, who's 25, has experienced good and bad days trying to work back. The 25-year-old from Czechia has not played since getting concussed when he was hit from behind by Chicago's Jason Dickinson on March 15.
