"The Washington Redskins answered one of their biggest free agency questions Tuesday by agreeing to terms of a contract extension with Santana Moss, their reigning top receiver.

The sides settled on a three-year, $15 million deal that includes $6 million guaranteed, according to an ESPN report. A source with knowledge of the deal confirmed the agreement and the terms.

The Redskins would not confirm the agreement, which cannot become official until Friday evening under league rules. Moss could not be reached for comment, and agent Drew Rosenhaus did not respond to several messages.

Moss, 32, has led the Redskins in receiving yards in each of the past six seasons. His 93 receptions last season were a career high, and his 1,115 yards were the second-highest single-season total of his career. Offensive coordinator Kyle Shanahan last year frequently deployed him out of the slot and put him in motion before the snap, tactics that exploited his shiftiness. Moss raved about the strategy, even as he became less of a deep threat.

Washington's first major roster move since before the NFL lockout brought some clarity to the team's offensive outlook.

Whether the Redskins will add another receiver, such as free agents Santonio Holmes or Sidney Rice, is uncertain. But now that Moss' tenure will continue, the Redskins at least will have the top three pass-catchers (Moss, tight end Chris Cooley and wideout Anthony Armstrong) back from a passing offense that ranked eighth in the NFL in yards last season.

"lets build on last season bro!" Armstrong messaged Moss on his Twitter account after news of the deal broke.

"U already knw!!! Lets go it bro," Moss responded.

Team officials spent Tuesday churning through their to-do list after the league re-opened for business at 10 a.m."
