Cowboys linebacker Ryan Fowler, a restricted free agent, a four-year, $10.5 million offersheet with the Philadelphia Eagles Sunday.
Fowler led the Cowboys in 2006 with 24 special teams tackles.
The Cowboys have seven days to match the offer, but sources within the organization say that is highly unlikely.
Fowler signed with Cowboys as a rookie free agent immediately
following the 2004 draft but then injured his back in offseason
workouts and was released. He was later re-signed and has been on the 53-man regular season roster on and off since.
