Australian James Troisi completes a trio of players whose contracts will not be renewed this summer.

Ramage, 24, was offered the chance to stay with his hometown club but has opted to pursue regular first-team football elsewhere.

Carr arrived in 2004 from Tottenham having earned a reputation as one of the best full-backs in England and had previously been linked with Manchester United.

But a series of injuries hampered his progress and he must now find alternative employment in the summer after 107 matches in four seasons at Newcastle.

"We wanted to keep Rammy (Ramage) but he wants to play regular football and I couldn't guarantee that here," Keegan told the club's website.

"He goes with our best wishes, as does Stephen Carr, who has been a great pro for this club. He wasn't offered a contract and I explained the reasons why."

Troisi made it as far as the bench but never made a full debut for the club.

"James has also gone. He has gone to play for Australia at the Olympics but he has not been offered a contract," Keegan added.
