The Australian Rugby Union (ARU), already under fire over their handling of Greg Smith's resignation as coach, have more unrest on their hands with their edict to stand down 12 Wallaby players from club matches for the rest of the season. Former New Zealand All Black great Grant Batty, now coach of Brisbane's Easts club, warned the ARU's effort to protect players could backfire with players being "underdone" for the tour to Argentina and Britain this year.

And Sydney's Randwick club, keen to have Wallaby half George Gregan free to replace New South Wales state halfback Chris Whitaker, who broke a leg last weekend, called for consultation between ARU and club medical staff.

The 12 players nominated to stand down from club rugby because of injuries or fatigue following medical advice were Marco Caputo, Troy Coker, John Eales, Michael Foley, George Gregan, Richard Harry, Stephen Larkham, Jason Little, Brett Robinson, Joe Roff, Ben Tune and David Wilson.

ARU managing director John O'Neill said the decision on each player had been carefully weighed up. "The decision to rest these players is not some whim, but is based on sound medical analysis," said O'Neill, who added the ARU was gathering data on the optimum number of games per season, which so far suggested between 24-28 matches.

Randwick chief executive Jim O'Brien acknowledged his club was anxious to regain Gregan, and would like the option of discussing it with him.

However, O'Neill left no doubt that the paymasters would be calling the tune.

"I understand the disappointment of the clubs who might have some players unavailable, but quite frankly, the game has changed. Our Wallabies are professional footballers."
