Mathew Leckie’s fourth World Cup campaign is in doubt after he suffers a hamstring injury, according to multiple reports. All three outlets say the problem is derailing his tournament and could limit whether he returns to the field. The reports describe Leckie as a veteran involved in Australia’s World Cup squad and note that his chances of coming back depend on how his hamstring recovers and whether the injury responds in time for him to be match-fit again. The uncertainty around his availability means Australia may need to plan for the possibility that he does not play again at the tournament, at least for an extended period. While the reports agree on the injury and its potential impact, they do not provide specific medical timelines or match participation outcomes. The situation is presented as fluid, with his World Cup participation potentially ending if recovery takes longer than expected.
