The Anaheim Ducks have added some center depth, signing Dennis Rasmussen to a one-year contract. Rasmussen became a free agent when the Chicago Blackhawks decided not to issue him a qualifying offer last month. No financials have been released so far. Playing in 68 games with the Blackhawks last season, Rasmussen scored just eight points but was an effective fourth line checker. With the Ducks seeing Nate Thompson move on to Ottawa, Rasmussen should be able to fill some of his role on the fringe of the roster.
