Nadal, who only recently returned from a stress fracture in the ribs, struggled badly at the back end of his match against the Canadian as he went down 1-6 7-5 6-2 in the last-16, Reuters reported.
"I had my foot again with a lot of pain. I am a player living with an injury – it is nothing new. It's something that is there," Nadal, a 10-times champion in Rome, told reporters.
Nadal's preparation heading into the French Open, where he will be bidding for a record-extending 14th title, has been far from ideal after he was also knocked out of last week's Madrid Open by Carlos Alcaraz at the quarter-finals stage.
"First thing that I need to do is to don't have pain to practice... it's true that during the French Open, Roland Garros, I going to have my doctor there with me. That sometimes helps because you can do things," said Nadal.
