Redskins tight end Fred Davis was cleared Tuesday to ramp up his physical activity and resume running as he continues to work his way back from a ruptured left Achilles tendon, according to a person with knowledge of the situation.

That person, who spoke on condition of anonymity to discuss personnel, expects the fifth-year pro to be completely healthy by the time the team begins organized team activities in May.

Davis suffered the injury seven games into the 2012 season. He was playing on a one-year franchise-tag deal in the hope of earning a long term contract. But now his contract is set to expire and he faces uncertainty for a second straight offseason.

A person with knowledge of the situation said last week that Davis was ahead of schedule in his recovery. The latest development, first reported by ProFootballTalk, is another positive sign for Davis, who in 2011 put up career numbers with 59 catches for 796 yards and three touchdowns in 12 games.

Davis missed the final four games of that season while served a suspension for failing multiple drug tests. But in 2012, he vowed to change his ways, and coaches and teammates were impressed with his new found maturity.

The Redskins could use the franchise tag on Davis for a second consecutive season, and would have to pay him about $6.5 million. But as of this week, the team hadn’t made a decision to do so. The Redskins are expected to wait until later in the spring when they can better gauge Davis’s health.
