Mark Cuban has been fined $50,000 by the NBA after admitting to leaking information from a Board of Governors meeting to a reporter.

"I appreciate the irony of your reporting on a fine that someone should, but won't, get fined for leaking to you," Cuban told ESPN.

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 had leaked the information, sources said.
