There were around 2,500 people in the stadium on March 6 - including MCs, boxers, staffers and the press, and not 10,000 as reported, it said.
However, the statement did not respond to the rumour that the Boxing Board had requested cancellation of the matches on March 6 in a letter sent to the management of the stadium dated March 4.
