The collapsing Blues could face a late shift in match venue against the Waratahs on Saturday night, as they try to continue New Zealand's winning streak against Australian sides.
The injury-hit Blues and erratic Waratahs are due to play on a suburban league ground with such a bad surface that it is being blamed for a series of bad knee injuries.
Brookvale Oval, the famous home to league's Manly Sea Eagles, has been described as a cow patch and treacherous.
Manly league chief executive Lyall Gorman has just admitted there is a potential problem at the sand-based ground, which has been re-named Lottoland under a sponsorship deal.
The Waratahs have called for a safety inspection which will take place today, conducted by the Northern Beaches Council which owns the ground. The Waratahs checked the field on Monday and supposedly had no problem with it. But NSW rugby reportedly raised "serious concerns" with the council on Tuesday.
