Giannis Antetokounmpo #34 of the Milwaukee Bucks drives to the basket against Bam Adebayo #13 of the Miami Heat during the second half at American Airlines Arena on March 02, 2020 in Miami, Florida.

Marc Lasry, co-owner of the NBA's Milwaukee Bucks, told CNBC on Tuesday that sporting events could possibly ban fans if the coronavirus outbreak worsens.

"If you're going to do it to basketball, you're going to do it to baseball," Lasry said on "Fast Money." "I hope we don't get there."

The billionaire hedge fund manager said games that exclude spectators could have more serious implications for the upcoming baseball season, as baseball stadiums can hold more people. He added that basketball games in Europe have already barred fans because of the virus and that the National Basketball Association could do the same if more people get sick.

The NBA issued a memo to teams on March 1 advising players to avoid high-fiving or giving fist bumps to fans and taking items to sign autographs. The memo also included tips on hand-washing.
