Matthew Out Of Windy City Open

England's world No5 Nick Matthew has been forced to withdraw from next week's Infor Windy City Open. The second PSA Super Series event of the year, in which the British Open champion was the fifth seed, gets underway in Chicago, USA, on Tuesday.

England's highest-ranked player sustained an ankle ligament tear this week in the PACE Canadian Classic in Toronto. The 26-year-old from Sheffield is currently undergoing intensive physiotherapy treatment back on home soil.

The revised draw elevates Australia's Cameron Pilley to 16th seed and promotes Canada's Shawn Delierre into the main draw. Pilley, from New South Wales, now takes on a qualifier in the first round, while Delierre will meet fellow Canadian Graham Ryding, the 15th seed.

The star-studded line-up for $80,000 event is led by Amr Shabana, the world number one from Egypt who is expected to meet world No2 David Palmer, the defending champion from Australia, in the final.
