Washington Redskins quarterback Robert Griffin III is expected to open training camp on the physically unable to perform list, according to sources, giving him more time to heal and the team an extra roster spot to bring another quarterback to training camp.

The NFL already has asked the Redskins as to when they might be able to expect Griffin to return from his knee injury so the league can know how early in the season to schedule Washington for nationally televised games, sources said.

The Redskins have told the league they are uncertain when to expect Griffin back and they will not know until sometime this summer.

TV networks also have asked the NFL if it's possible to wait on any nationally televised games that involve the Redskins until they can have a better idea when Griffin might return from his knee injury.

But those answers won't be known before the NFL's regular-season schedule is released in April. 

Griffin won The Associated Press 2012 NFL Offensive Rookie of the Year award Saturday after setting the NFL record for best passer rating by a rookie quarterback and leading Washington to its first NFC East title in 13 years.

Griffin, who underwent surgery to repair a torn ACL and LCL last month, said: "It's truly a blessing to be up there -- to be able to stand, first and foremost."
