Former Washington Redskins tight end Chris Cooley remains realistic about his possible comeback -- and knows it might not happen until after the season begins.

Cooley said during his show on ESPN980 that he did talk to Arizona before it signed Jermaine Gresham. But he said doesn't anticipate a team signing him before training camp. And he added that he doesn't want to get too excited about whether or not it will happen.

"I'm not holding out hope," said Cooley, who last played in the 2012 season.

He will be in Richmond this week for Redskins training camp, which begins Thursday. Even if the Redskins were interested, Cooley said the team was prohibited from signing him, which a team source confirmed. Cooley said a team can't sign a player in the same year that it's already paying for a different service. In addition to his daily radio show, Cooley serves as an analyst on Redskins games.
