Sharapova had her deal with Nike suspended by the sportswear giantsfollowing her failed drugs test at the Australian Open earlier this year.

She is still wearing Nike shirts as she was pictured in one while leaving the gym on Tuesday.

The Former world number one revealed on Monday, March 7 that she tested positive for Meldonium at the season's opening major in Melbourne in January.

And Nike wasted little time responding to the situation, releasing a statement which read: "We are saddened and surprised by the news about Maria Sharapova.

"We have decided to suspend our relationship with Maria while the investigation continues. We will continue to monitor the situation."
