Nick Kyrgios's 11th-hour withdrawal from the French Open has left red-faced officials in a mad scramble to find a replacement to play Bernard Tomic on Monday.
Tomic won't know who he plays - if anyone at all - until the morning of his scheduled 11am start to his first-round match.
In unprecedented and rather comical scenes at Roland Garros, the tournament ran out of "lucky losers" - players who failed to qualify - available to fill the void in the main draw.
A glut of withdrawals left seven lucky losers already promoted to the 128-man main event, with Egyptian Mohamed Safwat the only unsuccessful qualifying entrant to sign up on Sunday.
Bulgarian fourth seed Grigor Dimitrov only learnt he was playing the 182nd-ranked Safwat 20 minutes before taking to Court Philippe Chatrier.
Dimitrov still managed to beat the first Egyptian man to make a grand slam main draw in 22 years 6-1 6-4 7-6 (7-1) to safely progress to the second round.
Finding an opponent for Tomic was proving far more troublesome for the International Tennis Federation (ITF) and French governing body.
Prajnesh Gunneswaran would have been next in line but was ruled out of the race for the eighth lucky loser spot because he was already in main draw of another tournament this week, a Challenger event in Vicenza, Italy.
It then emerged Gunneswaran could actually take the lucky loser's spot if granted a release by the tournament supervisor in Vicenza.
Alas for the Indian battler, Gunneswaran had already departed Paris long ago.
The whole debacle prompted a fan on Twitter to urge Tomic's countryman Thanasi Kokkinakis - who lost in the second round of qualifying - to "fly back to Paris".
Kokkinakis, who is in fact still at Roland Garros training, saw the funny side and replied: "I wish I knew how this worked?? f***"
In the end, Argentine Marco Trungelliti emerged on Sunday night as the player likely to take on Tomic - and take half of Kyrgios's first-round prize money - a cool 40,000 euros ($A62,000) - or more if he beat Tomic.
Nothing was certain, though, with Trungelliti forced to embark on a frenetic 10-hour drive back from Barcelona to sign up for the lucky loser's spot on Monday morning.
Photos of Trungelliti in a car with mates and his tennis bag were already circulating on social media.
But should Tomic fail to land an opponent, he would earn a walkover through to a second-round date with either Romanian Marius Copil or Italian Marco Cecchinato for an unlikely spot in the last 32 in Paris for the first time.
The spate of withdrawals stems from a new rule introduced this year by the ITF to combat injured players retiring mid match in the first round of the slams and then collecting their cheques.
Now, players who do not "perform to the required professional standard" in the first round, including by retiring, also risk being fined their prize money.
Ironically, Tomic was fined a third of his STG35,000 ($61,700) prize money for unsportsmanlike conduct last year at Wimbledon, after saying he felt "bored" and "couldn't care less" following a straight-sets defeat on day one.
Any repeat this year and he would lose the lot.
