The NBA fined Dallas Mavericks owner Mark Cuban $50,000 after he admitted to leaking information from last week’s Board of Governors meeting to a reporter, sources told ESPN.

The fine was not publicly announced, but the league office issued a memo to inform teams.

Sources said Sacramento Kings owner Vivek Ranadive expressed concern that information about the vote to allow coaches’ challenges was being reported while the meeting was still in session.

Cuban immediately admitted that he leaked the information, sources said.

Cuban was fined because it is a violation of league rules to talk to outsiders about Board of Governors business.
