Pearson returns after injury Athletics. Olympic champion Sally Pearson says she's back training without pain following a hamstring injury. The 100-metre hurdles gold medallist missed this summer's track season because of a torn hamstring but began hurdling again this week. "Everything's looking up," she said. I started hurdling on Monday, which is probably almost eight months since I competed at the Olympics. Chance for Tomic, says Rafter Tennis. Pat Rafter says Bernard Tomic still has to prove his commitment to the Davis Cup but believes he can take a giant leap towards doing so under trying conditions against Uzbekistan. Tomic returns for Australia after ending his feud with Rafter and shapes as the key component in the must-win Asia/Oceania second-round tie starting in Namangan on Friday. The Australian team will attempt to earn a shot at returning to the top 16 for the first time since 2007. Armstrong back with a splash Swimming.
