Coleman, who is one of the favourites to replace Ian Holloway as Crystal Palace boss, was scheduled to unveil his squad for the friendly to the media on Friday.
But the Football Association of Wales have decided they did not want the press conference to be overshadowed by questions over Coleman's future and his continuing links with his former club.
"We have discussed it with Chris and we have decided to release the squad by email because it would be a worthless exercise holding a press conference when all the questions will be about Chris' contract and Crystal Palace," an FAW spokesman said.
"We are not hiding anything. Chris will be in Cardiff on Friday."
The friendly against Finland at Cardiff City Stadium on November 16 could prove to be Coleman's last in charge of the national side after talks with FAW officials over a new two-year contract stalled.
Coleman admitted last month a final decision over whether he would continue in the role is unlikely to be taken until after the clash with the Finns.
He has been constantly linked with the vacancy at Palace since Holloway's departure, although the FAW have insisted they have received no approach for Coleman's services.
