Nadal was just about to enter the court for his third-round clash with Benoit Paire when what would become persistent rain began to fall - forcing organisers to abandon the remainder of the day's scheduled action.
Should 11-time grand slam champion Nadal prevail against the world number 33 from France, he will be back in action later on Friday to play the winner of the match involving Albert Ramos and sixth seed Kei Nishikori.
Just three matches were completed on Thursday, with fourth-seeded Spaniard Nicolas Almagro among the lucky few as he saw off compatriot Marcel Granollers 6-3 6-4.
Almagro's opponent in the last eight is Argentina's Juan Monaco, the seventh seed, who progressed after a 6-0 7-6 (13/11) win over 10th-seeded Frenchman Jeremy Chardy.
Brazil's Thomaz Bellucci is into the quarter-finals after a 4-6 6-1 6-3 win over Dmitry Tursunov, who failed to build on his upset of top seed David Ferrer in the previous round.
Martin Klizan was leading Philipp Kohlschreiber 6-1 6-7 (2/7) 4-3 when the rain arrived to force the suspension of their second-round match.
