American basketball player, Jenrry Mejia of New York Mets, has been suspended for 80 games without pay after testing positive for the banned substance stanozolol.
The 25-year-old will not be able to play again until July and would be ineligible for the Major League play-offs if his team qualifies.
"I know the rules are the rules and I will accept my punishment," Mejia was quoted as saying by bbc.com on Monday.
"But I can honestly say I have no idea how a banned substance ended up in my system."
