SYDNEY _ Andrew Bogut's luckless run continued this week with the Australian star ruled out indefinitely with a serious ankle injury that threatens his NBA season. His latest setback occurred when the Milwaukee centre landed awkwardly on the foot of Houston guard Kyle Lowry while attempting to block a shot during the Bucks' victory over the Rockets this week. Bogut had hoped for the best, praying that his luck might have turned around, but MRI scans yesterday confirmed the left ankle fracture. It looks certain to rule the 27-year-old out of All Star contention and has the potential to ruin the rest of his season.
