The NFL has told the players' union that it will stop providing health care for players and their families in March if the two sides do not reach a new collective bargaining agreement. During an appearance with Minnesota Vikings fans on Tuesday, NFLPA executive director DeMaurice Smith said he was working to figure out a plan to ensure medical coverage for players and their families should they be locked out. Smith said he is dealing "with players where some of them have children who need heart transplants. We have several players who have children who are on kidney dialysis. We will have over 100 players who will have children who are born in the March, April, May timeframe. Right now all of those players need health insurance." NFL spokesman Greg Aiello said it's one more reason to reach an agreement. He also pointed to the federal COBRA law that allows employees to continue their existing coverage without interruption at their own expense or the expense of their union. "This means that no player or family member would experience any change in coverage for so much as a single day because of a work stoppage," Aiello told the Associated Press in an e-mail. "The union surely knows this and there is no excuse for suggesting otherwise." During the NHL lockout in 2004-05, the NHL players' union paid for substitute coverage. Source: CBS Sports
