Raonic complained of pain in his foot following the match but has insisted that he underwent an MRI scan only as a precaution.
He told reporters: "I rushed out to get a quick MRI on my foot, but the foot is good.
"It's just pain from use. It was really nothing until 48 hours ago. There's nothing there to affect my participation in the Davis Cup matches.
"I'll be there, if called upon. I just need a few days to maximize my treatment to make it go away and get well."
Canada face Davis Cup favourites Spain in a home tie beginning on Friday, February 1.
