Andy Murray has played down any injury concerns after he received treatment during Wednesday's Rogers Cup win over Flavio Cipolla.
The Olympic gold and silver medallist called for the physiotherapist to look at his knee during the second-round victory over the Italian in Toronto.
"I was stiff and sore," said Murray. "I had a lot of matches at the Olympics and this was my first match on a hard court in four months."
The Brit will meet Canadian Milos Raonic for a place in the quarter-finals.
