( CNN ) Juan Martin Del Potro has pulled out of the Australian Open , citing persistent concerns surrounding a wrist injury that has ravaged much of his past year . The 2009 US Open Champion has struggled with wrist injuries since 2010 and had not played for over ten months . Yet it appeared that Del Potro 's injury jinx was behind him after reaching the quarter final of the Sydney International last week . But the former world number four decided that the year 's first grand slam had come too soon . `` It 's a pity that I can not take part in such an important tournament , yet this is another episode in the long way to recovery , '' Del Potro wrote on his Facebook account . `` I will follow the advice of my doctors and try to return as soon as possible . '' Del Potro has slipped to 276 in the world rankings since injuring his left wrist in February 2014 , but has indicated that he aims to play again in March , possibly in Miami or at Indian Wells . `` I appreciate the support that I received since I announced I was playing in Sydney , '' he added . `` It was amazing . '' This year 's Australian Open has been hit by a series of exciting , big -- hitting players either pulling out injured or struggling to reach peak fitness before the tournament begins Monday . US Open champion Marin Cilic pulled out at the start of the year , as did Frenchman Jo-Wilfried Tsonga whilst Rafael Nadal has complained that he is still feeling the effects of an operation to remove his appendix . The biggest uncertainly , however , concerns the fitness of Australia 's Nick Kyrgios . The teenage sensation arrived at Wimbledon an unknown but reached the quarter final after beating Nadal , announcing himself as one of the game 's most exciting young talents . Kyrgios has been desperate to get fit for his first 'home ' grand slam since following his breakthrough season and had taken the past four months off to try and heal a persistent back injury that had cast doubt on his participation . Last week it looked like he too might pull out but the 19-year-old confirmed he will be in Melbourne Monday . `` I 'm obviously feeling it . It 's not 100 per cent . But , you know , I 'm good enough to compete , '' Kyrgios told the Sydney Morning Herald on the eve of the tournament . `` I 'm noticing improvements every day ... Yeah , I think I 'm ready to compete . ''
