Player movements: Bulldogs, Cowboys

Bulldogs prop Nate Myles is set to become one of the hottest properties on the open market, with seven NRL clubs chasing the Queensland enforcer's signature.

Myles is almost certain to leave the Bulldogs at the end of the season, with Brisbane, North Queensland, Melbourne, Canberra, Souths, Sydney Roosters and the Gold Coast all queuing up for his services.

The 20-year-old, who debuted for the Maroons in the first State of Origin this year and was outstanding in their 30-6 thumping of NSW last week, will test his value on the open market after June 30.

Elsewhere, a rival club has made an expression of interest for North Queensland sensation Johnathan Thurston, less than 24 hours after the NRL said it would scrap its contentious June 30 anti-tampering deadline.

The move comes amid fears the player market will now become an ugly free-for-all where players will be courted despite having long-term deals with their existing clubs. Thurston's manager Sam Ayoub says he has fielded an inquiry from a club official hopeful of luring the Kangaroos playmaker when his contract with the Cowboys expired at the end of next season.

Cowboys chief executive Peter Parr says while the move is bordering on a breach of the anti-tampering rules, he is powerless to do anything about it.
