Andy Murray’s rehabilitation from hip surgery is going so well that the former world No 1 could return to action sooner than expected, according to Sky sources.

Murray has been targeting a return for the grass-court season having been sidelined since last year’s Wimbledon due to a hip problem that he had surgery on in the new year, after breaking down again just before the start of the Australian Open.

Murray, who turns 31 in May, has been back in the gym working on the bike, Versaclimber, weights and taking regular pilates classes, with plans of returning to the court towards the end of March and the intention of being match ready in time for the grass season.

And with his rehabilitation from injury going better than expected, he could be back sooner than Wimbledon.

The signs appear to be very positive for the Scot, who has indicated his intentions of travelling overseas for warm weather training in the next couple of months, although it is dependent on when he returns to the court.
