A leg issue is an ongoing stumbling block for Milos Raonic.
A right hamstring injury has forced Raonic out of Miami.

The third-seeded Canadian withdrew from the Miami Open prior to this scheduled match with Jared Donaldson on Grandstand court.
Raonic, who pulled out of last month’s Delray Beach final and later withdrew from Acapulco and Indian Wells due to the same injury, said he won’t return until he feels 100 percent fit.
"It's related to the previous injury I sustained almost four weeks ago in Delray," Raonic told the media in Miami. "It’s the same muscle up in the hamstring up high. It got progressively worse after my first round after practicing yesterday. It seemed like it was not possible for me to compete today without putting myself at risk.
“I think that the perspective is going to change. To come back when I feel I’m 100 percent. So that could be who knows and how long? It could be in two weeks. I think the ideology behind when I’m back playing matches is it will be that’s the best shape my body can be in.”
The walkover sends 20-year-old Rhode Island native Donaldson into his first Masters round of 16 where he will face either Jiri Vesely or 13th-seeded Jack Sock.
Raonic hit some serves about 90 minutes before his scheduled match, but could lacked the explosive leg lift on serve.
"I've always been the kind of person that gets the confidence through the work rather than matches, constant matches," Raonic said. "So I've been fortunate in that sense, because I've had to numerous times skip little periods of time. This time it's a little bit more difficult, because after the last injury preceding the Australian Open I was out; got into shape, not the best shape; and then got hurt shortly after and then I was out again."
