Milos Raonic has pulled out of the Miami Open ahead of his third round match against Jared Donaldson.

Raonic told the media, "It's related to my previous injury. It's the same muscle, up high in the hamstring. It got progressively worse after my first round, after practicing yesterday, and it seemed like it was not possible for me to compete today without putting myself at significant risk.

“Right now the perspective is going to change a little bit. Obviously the goal through these tournaments being on hard courts was that I can come back as soon as I feel ready. I think that that perspective is going to change to come back when I feel like I'm 100 per cent. That could be in two weeks; that could be a little bit longer. I think the ideology behind when I'm back playing matches and competing, it will be in the sense that that's the best shape my body could be in.”

Raonic was forced to pull out of the BNP Paribas Open earlier this month due to the same injury. He attempted to give it a go after warming up on Grandstand court, but was unable to proceed. The Canadian had defeated Viktor Troicki in Friday’s second-round.
