The person Friday spoke on condition of anonymity because the league has not announced the schedule for the upcoming season. The NHL awarded the game to Washington in September. The league has been considering three venues in the Washington area: Nationals Park, RFK Stadium and FedEx Field. Capitals owner Ted Leonsis has said he would prefer to play the game in D.C., which would rule out FedEx Field in the Maryland suburbs. The Blackhawks have played in the New Year’s Day game once before, having hosted it at Wrigley Field in 2009. Richards out in NYThe New York Rangers are buying out the contract of veteran forward Brad Richards, creating much-needed salary-cap space and parting ways with New York’s de facto captain one week after being eliminated from the Stanley Cup Finals. Both the Rangers and Richards’ agent, Pat Morris, confirmed the move Friday. Richards, a Stars player from 2008-2011, had six years remaining on the nine-year, $60 million deal, and this move will remove his $6.67 million salary-cap charge. Richards will receive two-thirds of the remaining money to be paid out over 12 years — a total of $12.6 million.
