TOKYO -- Milos Raonic has pulled out of Canada's David Cup World Group tie against Japan with a left foot injury.
Raonic, who withdrew Thursday, will be replaced by Peter Polansky who was in Tokyo as a reserve but now will be counted upon heavily.
Polansky will face a tough task in the opening singles match Friday against world No. 18 Kei Nishikori.
Nishikori will be looking to improve on his current four-match Davis Cup winning streak and an overall 10-2 singles record in the team tournament.
