Former world number one Andy Murray has suffered another injury setback after withdrawing from the Miami Open with a left groin injury.
Murray had been scheduled to return to action after missing the recent event in Dubai following the birth of his and partner Kim Sears' fourth child.
However, the ATP said on Tuesday that Murray would be missing with a left groin injury.

Murray missed the Australian Open earlier this year after contracting Covid, leaving him unable to travel to Melbourne, but did play in last year's US Open and delayed French Open. He was knocked out in the second and first rounds respectively.
The latest setback, of which the severity is not known, will now raise questions as to Murray's plans before the tour returns to grass.
There has yet to be any indication as to his clay court plans.

Our view – More frustration for Murray

How difficult is it proving for Murray to string some matches together?
From a pelvic problem that disrupted the end of his 2020 season to missing the Australian Open after testing positive for Covid-19 and then having to withdraw from Miami – a city where he says he feels "comfortable" – due to a groin issue. Murray can’t seem to get a break at the moment and it’s problematic as he tries to regain full match fitness.
He has said he “genuinely” believes he can win Wimbledon this summer, but to even come close to achieving that he will need to get tournaments under his belt beforehand.
Attentions now turn to clay, a more forgiving surface on the body but not Murray’s strength – and a surface he has only played one match on since June 2017.
However, he desperately needs to play and start winning matches again – he’s only won once on the ATP Tour this year – so, fitness permitting, expect him to be quite busy over the next few months.
