Unbeaten junior middleweight Tim Tszyu could be looking for a new opponent, as Michael Zerafa has been hospitalized with a yet to be disclosed rib-stomach injury, according to WA Today.

The paper reports that Zerafa was scheduled to fly from Melbourne to Sydney on Wednesday for a series of promotional commitments, but missed the flight due to the unknown ailment.

The fight is scheduled for July at Newcastle - and the venue is already sold it.
