Speedway rider Darcy Ward has undergone spinal surgery after being involved in a track crash in Poland on Sunday. Ward, currently on loan to Elite League club Swindon from champions Poole Pirates, was riding for Polish side Zielona Gora against Grudziadz. Zielona Gora's club doctor confirmed the Australian is breathing on his own and is aware of his surroundings after a two-and-a-half hour operation. The 23-year-old's condition is described as stable. A full prognosis is not likely to be known until Wednesday.
