Special teams coach Rich Bisaccia has been released from the remainder of his contract and is expected to join Jon Gruden in Oakland. But sources said the Cowboys want to retain running backs coach Gary Brown and are working to make that happen.
Matt Eberflus, the team's passing game coordinator and linebackers coach, is another assistant whose contract has expired. There appears to be interest in him around the league, but sources said the Cowboys hope to keep him in the fold as well.
The status of receiver coach Derek Dooley and offensive line coach Frank Pollack was unresolved as of Friday afternoon.
