Sunderland boss Lee Johnson feels "let down" by the English Football League for not providing "clarity" on whether Tuesday's game with Wimbledon should go ahead following a Covid-19 outbreak.
The new Black Cats manager was without eight affected first-team players.
"That game should have been called off. No doubt in my mind," Johnson told BBC Radio Newcastle following a 1-1 draw.
The EFL said in a statement that it was Sunderland's decision not to call it off - but the club had felt "unclear".
"Throughout our extensive discussions on Tuesday, it was made clear to the management of Sunderland that the option existed for them to inform the league they were unable to fulfil the fixture," said the EFL's statement.
