well, I found the answer to this question. I thought wrong.
CHARLOTTE, N.C. (Feb. 23, 2006) -- The Carolina Panthers protected running back DeShaun Foster from free agency by naming him their transition player.
Foster is now guaranteed $5.13 million next season if he doesn't sign a long-term contract. Foster can still talk to other teams when the NFL's free agent period starts, but the transition tag gives Carolina the right to match any offer.
The Panthers just took a step towards bringing DeShaun Foster back.
If the Panthers choose not to match any offer Foster might receive, they would not receive any compensation if Foster signed elsewhere.
Carolina has until March 17 to reach a long-term deal with Foster. If no deal is reached at that point, they will have to wait until July before beginning negotiations with Foster again.
