How the draw will work, depending on what happens first
The Australian Open draw is happening in half an hour, but it could shape up very differently if Immigration Minister Alex Hawke makes a decision very soon.
If Djokovic, currently seeded number one, withdraws (or is withdrawn) after the draw, he would be replaced by the fifth seed, which is currently Russian player Andrey Rublev.
But if Djokovic were to withdraw after first day's order or play is release, he would be replaced by a lucky loser, as New York Times tennis correspondent Christopher Clarey explains.
