Outstanding Viva Pataca is a '50-50 chance' to have a new partner in the Citi Stewards' Cup on January 24, according to trainer John Moore following a progress report on Darren Beadman yesterday. Beadman returned to Sydney last week to seek specialist treatment after being unable to complete his rides for the second meeting in a row on New Year's Day, and chief steward Jamie Stier signed yesterday's release on his condition. Beadman told stewards he had 'no power' in his right leg when he crouched down to push out his only mount last week, and the report from Dr Grace Bryant of South Sydney Sports Medicine stated the jockey has a 'strained/bruised right femoral nerve in his lower back, a nerve associated with the quadriceps muscle at the front of the thigh'. She said Beadman's right leg showed 'decreased quadriceps muscle bulk and decreased power of the hip flexors and knee extension.' The report said Beadman's condition was improving with intensive treatment, but he would be unlikely to resume riding for several weeks. 'We'll keep following Darren's progress carefully, but we don't want him to come back this time until he is 100 per cent right,' Moore said. 'It looks like he's only a 50-50 chance to ride in the Stewards' Cup at this stage. 'I don't want to do anything about a different rider for Viva Pataca until we know the situation for sure, but if Darren can't ride him then we'll be looking wherever we have to for the right jockey - that may mean offshore or we may look at whoever is having the most success for the stable in Hong Kong leading up to the race,' he added. Speaking from the Magic Millions sale at Australia's Gold Coast, Moore said Viva Pataca was a certain runner in the Stewards' Cup over 1,600m. 'We don't want the race to be a forgone conclusion for Good Ba Ba and if Viva Pataca produces the sort of mile run he did first-up this season in the Sha Tin Trophy then he will be competitive in anything,' Moore said. 'He needs the race to keep him ticking over for the Gold Cup in February. I don't want him going into a Group One race like that without having had a run for two months.'
