The seven-fight boxing card scheduled Saturday night at Capital Centre was canceled yesterday because the Maryland State Athletic Commission revoked its sanction when the event's promoters could not produce a bond of $45,000 to guarantee the purses.

However, Charles Rosenbleet, president of Star Sport Inc., which he said was co-promoting the event with Capital Centre, said he is filing suit today in the Circuit Court of Prince George's County to have the commission sanction reinstated.

Two prominent District fighters were on the card. U.S. Boxing Association cruiserweight champion Boone Pultz (13-0) was scheduled to defend his title against Carlos Hernandez of Union, N.J. North American Boxing Federation welterweight champion Maurice Blocker (22-0) was to fight Juan Alonso Villa of Guadalajara, Mexico.

Rosenbleet said Chester O'Sullivan, head of the state athletic commission, told him and Pat Darr, director of events at Capital Centre, in a meeting last Wednesday that the expense bond had to be increased from its original $2,000 to $45,000. He said O'Sullivan told him the money, in bond form guaranteed by an insurance company, had to be presented to the commission by the boxers' pre-fight physicals yesterday at noon.

Rosenbleet said he was informed by "a number of insurance companies" that a bond of that figure could not be produced for at least two to three weeks. He said he asked O'Sullivan to postpone any action until today, but he refused. Rosenbleet also said he offered to put up cash or a bank letter of credit but was told the bond had to be guaranteed by an insurance company.

Capital Centre spokesman Bob Zurfluh said, "They Star Sport are the promoters. We have the building. We were going ahead with our end of the deal of advertising and publicity. We were not about to put up the bond for the purses, which should be the responsibility of Star Sport ."

The bond is required to ensure the promoter can pay all fight costs, including the purse of each boxer. The commission increased the bond at last week's meeting for Saturday's card to ensure the event's total purse of $30,000 was covered.
