Pompey have been told a refereeing official got the rules of the game wrong at Newport County.
Boss Andy Awford was fuming with the display of referee Michael Bull in Saturday’s 1-0 loss.
Two penalties not awarded and Aaron O’Connor’s role in an offside position for Mark Byrne’s winner were the cause of his anger.
The assistant referee immediately flagged after the goal, but Bull controversially ruled O’Connor was not interfering with play.
Awford felt the fourth official, who had a perfect vantage point, should have been consulted – but was told by the referee’s assessor that wasn’t allowed.
The Blues boss, however, has since been informed by referees’ manager, David Allison, that isn’t the case.
Awford said: ‘I’ve spoken to the referees’ manager and the fourth official is allowed to intervene on major match-changing events. That’s despite the ref’s assessor saying that he couldn’t to me.
‘I’d say their goal on Saturday was a match-changing event!
‘I don’t criticise officials and I think this is the first time that has been the case.
‘But I’m stood a yard from the fourth official and could plainly see he was interfering with play. The fourth official is part of the team and should speak up.
‘What I don’t understand is why the assessor has said he can’t do that.
‘He’s wrong. He doesn’t know the rules.’
Despite having cause to feel his team have been wronged, Awford is now keen to put the issue to bed.
He added: ‘We aren’t a side who make excuses. The last couple of performances have been good and we need to carry that into Saturday.’
