Britain's Andy Murray has maintained his position on top of the men's Association of Tennis Professionals world singles rankings released on Monday, with 7.750 points.
There were no changes in this week's rankings, with Spain's Rafael Nadal on the second spot, followed by Switzerland's Roger Federer on third.
However, with Murray out of action because of a hip injury, Nadal has the opportunity to take top spot for the first time since July 2014 if he reaches the semi-finals of the Coupe Rogers Tournament in Montreal, which kicks off this week.

1. Andy Murray (UK) 7,750 points
2. Rafael Nadal (Spain) 7,465
3. Roger Federer (Switzerland) 6,545
4. Stan Wawrinka (Switzerland) 5,780
