Middleweight boxer James De La Rosa came up positive for the banned diuretic Furosemide in a drug test taken for his bout last month against Marcus Willis, according to Keith Kizer, executive director of the Nevada Athletic Commission.
A complaint against De La Rosa has been issued and served, Kizer said. The nine other boxers who appeared on the April 12 card at the Treasure Island Casino in Las Vegas came up negative in the states drug-screening panel.
De La Rosa lost an eight-round majority decision to Marcus Willis. The bout took place on the non-televised undercard to a broadcast of Showtimes ShoBox: The New Generation. The defeat dropped the 25-year-old to 21-2 with 12 knockouts. (Willis improved to 13-2-2 with 3 knockouts).
Other boxers have tested positive in recent years for Furosemide, which is also known as Lasix. Those names include Ricardo Mayorga and Rosendo Alvarez in 2006, Julio Cesar Chavez Jr. in 2009, and Joan Guzman in 2010.
