Nike has suspended its relationship with Maria Sharapova following the five-time grand-slam champion's failed drug test at the Australian Open earlier this year.
The former world No. 1 revealed on Monday that she tested positive for Meldonium at the season's opening major in Melbourne in January.

Sharapova had been taking Meldonium for a decade due to health reasons and said she was not aware it was added to the World Anti-Doping Agency's (WADA) list of prohibited substances as of Jan. 1.
And Nike wasted little time responding to the situation, releasing a statement Monday night 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."
Sharapova — who lost to Serena Williams in the quarter-finals at Melbourne Park — will be provisionally suspended effective March 12, the International Tennis Federation said.
The 28-year-old had already withdrawn from this week's BNP Paribas Open at Indian Wells due to a left forearm injury, which has proved troublesome.
