Those planning to snap up tickets for UFC 173 early are out of luck – at least for now.

Officials announced that the planned pre-sale of tickets for the Memorial Day weekend event has been postponed after the cancellation of the main event.

Chris Weidman was expected to defend his UFC middleweight title against Lyoto Machida, but Weidman was forced to withdraw after a knee injury. He will now meet Machida in July.

Plans for a new main event for UFC 173 are expected to be confirmed in the coming days. A pre-sale date for tickets will be announced after the headline fight is made public.
