Jan Molby said: "I get the impression that both players can't wait to leave and go back home. That may be just as well because neither feature in my plans for next season."
The pair made over 150 appearances between them since joining in October 1999.
Meanwhile, Rodney Rowe, Ben Morley and Adrian Caceres also look set to be released when their contracts expire at the end of the season. Jason Van Blerk may be kept on after featuring in Jan Molby's team selections, though with other players such as Andy Holt, Matt Wicks, Mike Price, Steve Burton and Nathan Peat all under contract for next season the Aussie may go as a cost cutting measure.
