Notably, Djokovic has already been drawn for Round 1 against his countryman Miomir Kecmanovic. However, if he is ruled out of the tournament before the day's order of play is announced, Andrey Rublev of Russia will move into the world number one's bracket to face Kecmanovic. But, if it all happens after the day's OoP is revealed, the defending champion gets replaced by a lucky loser. Walkover will only happen if he has played a match in the competition.
