The Eagles tendered defensive tackle Antonio Dixon, a restricted free agent, at a second-round level on Monday.
If another team attempts to sign Dixon before April 20, the Eagles would have seven days to match the offer or receive a second-round draft pick as compensation.
Dixon's salary for the year will be $1.927 million.
The fourth-year defensive tackle suffered a season-ending triceps tear in October, but is said to be on course to return by the start of spring practices. Dixon, a former undrafted free agent of the Redskins, was acquired by the Eagles in 2009 and developed into one of their best run-stopping defensive tackles.
Dixon is the Eagles' lone restricted free agent.
Free agency and the start of the league year opens Tuesday at 4 p.m. The Eagles have ten unrestricted free agents, including guard Evan Mathis and defensive tackle Derek Landri.
