USA Wrestling has received notification that the International Olympic Committee has responded to the U.S. Olympic Committee's request to change the U.S. Olympic team roster at 76 kg in Greco-Roman wrestling.    In a letter to USOC Managing Director and General Counsel Mark Meudeking on August 31, IOC Sports Director Gilbert Felli responded that the IOC has agreed to grant the requested substitution of the entry, with Matt Lindland in the place of Keith Sieracki.    USA Wrestling has also received notice that an appeal of the decision by Judge James Zagel naming Lindland to the team is still pending.    The text of the IOC letter follows:    Re: Entry substitution    Dear Mr. Muedeking,    We acknowledge receipt of your letter dated 29 August 2000 addressed to the IOC President, the contents of which have been duly noted.    As your request was made pursuant to a court's order, the IOC has agreed to grant the requested substitution of entry, i.e. Mr. Matthew Lindland in the place of Keith Sieracki.    Yours sincerely,    Gilbert FELLI  Sports Director
