Swansea City say an "administrative error," is to blame for the club announcing the proposed return to the board of Leigh Dineen.
Dineen, Swansea's vice chairman, left the board in July after the American takeover of the club.
Companies House records showed Dineen had been restored to the board with documents being filed on November 15.
Swansea's Supporters' Trust, which owns a 21% stake in the club, say Dineen was reappointed without their knowledge.
Dineen, also the club's commercial manager, will now have his proposed return discussed at a board meeting in December.
