Australia's Usman Khawaja reveals he secretly battled serious illness throughout his career

Ex-Australia opener Usman Khawaja has revealed he secretly battled rheumatoid arthritis throughout his career. Khawaja was diagnosed with the disease in 2009 when he was 22. He said he initially feared he would die after severe knee pain left him unable to walk even 10 metres. He kept the autoimmune disease hidden from teammates, including his childhood friend David Warner.
