Australia captain Aaron Finch says it will be up to Glenn Maxwell whether he plays in Saturday's Cricket World Cup clash with South Africa after the all-rounder was struck on the forearm during a horror net session for the side. Shaun Marsh was put out of the tournament on Thursday by a short delivery from team mate Pat Cummins which hit him on the wrist, and shortly afterwards Maxwell was sent to hospital by a blow from seamer Mitchell Starc.
