Mortimer unhappy at Sherwin leak

Bulldogs boss Steve Mortimer says he's disappointed at Brent Sherwin's manager for leaking news the classy halfback is poised to leave the NRL club unless it offers him a better deal.

Contract negotiations between the premiership favourites and Sherwin have broken down less than a week after he was named in the 33-man NSW State of Origin squad.

Mortimer says he's disappointed that player agent Mark Rowan went to the media with what he believed had been confidential information.

The Bulldogs face a monumental task in re-signing a host of high-profile players who come off contract at the end of this season, including Sherwin, Nigel Vagana, Luke Patten and Willie Talau.
