Stomach Problem For War Mouse Morris believes War Of Attrition´s poor run at Punchestown on Sunday was down to a stomach upset. Having won all his last three starts, including defeating Gold Cup winner Kicking King, the six-year-old was a very disappointing fifth in the John Durkan Memorial Punchestown Chase. Originally a virus was thought to be the reason for his performance, as a couple of Morris´ other horses ran badly and several different Irish yards have been beset by illness this season. However, Morris now thinks his horse could make a return to the track in the Lexus Chase at Leopardstown on December 27. 'Although I haven´t got all the results of the tests yet, we have established that it is not a virus but acid in their tummies,' the trainer told the Racing Post. 'It´s not much and a couple of easy days should put War Of Attrition and the others right. He could easily run over Christmas.' (C) PA Sport
