Serena Williams' husband, Alexis Ohanian, was seen wearing a drugs awareness shirt at a 2019 US Open tennis match Monday.

Ohanian could be seen with a shirt from the charity D.A.R.E. during Williams' first round clash against Maria Sharapova, which was their first battle since Sharapova was suspended for two years by the International Tennis Federation (ITF) in January 2016 after testing positive for a banned substance.

D.A.R.E (Drug Abuse Resistance Education), is a Los Angeles organization that runs police officer-led classroom lessons in schools to help promote drug free life.

Ohanian, the Reddit and Initialized Capital cofounder, made no comment on his choice of attire on the day, however did "like" a number of posts from users who had pointed out the shirt on Twitter.

It is unclear whether Ohanian and D.A.R.E are affiliated. Business Insider contacted the charity but are yet to hear back.

Williams beat Sharapova 6-1, 6-1 in less than an hour to set up a second round match with 17-year-old wildcard Caty McNally, whom she faces Wednesday.

Sharapova failed a drugs test during the 2016 Australian Open, testing positive for the banned substance meldonium.

The Russian had been taking meldonium 10 years prior to the failed test for medical reasons, however the substance was only added to World Anti-Doping Agency (WADA)'s banned list on January 1 2016, 26 days before she tested positive.

Sharapova was originally banned for two years by the ITF but following an appeal at the Court of Arbitration for Sport (CAS), the ban was reduced to 15 months.

She returned to tennis in April 2017, and has since won the Tianjin Open in October 2017.
