Haroldeans won the original tie earlier this month on penalties, but Maccabi appealed to competition organisers that match referee Ray McLaughlin broke the rules by playing only 10 minutes’ extra-time each way, rather than the required 15 as he had to get to another match.
The National Football Committee ordered a replay, but Haroldeans only agreed after researching their options.
The Merseysiders have lost both their matches since the original Morrison tie, with club chairman Saville insisting the decision may have “a psychological impact on the team”.
Saville confirmed the Morrison replay against Manchester will take place in Liverpool semi-pro officials, appointed by FA.
