Guy Whittingham admitted he was unsure whether John Marquis would see out the final 15 days of his loan following his Exeter omission.
The Millwall striker didn’t even make the 18-man squad on Saturday, despite starting the previous match at Torquay.
Instead Ryan Bird took his place and netted twice in the 3-2 success over the Grecians, while David Connolly was back on the bench after injury.
Marquis said his goodbyes to players and staff having been told by Whittingham of his decision before kick-off and the Blues boss expects the situation to be clarified today.
He said: ‘I told John before the game and I knew there might be a reaction from him.
‘He was disappointed because he scored two in six, it has been a team that hadn’t lost in five games, it’s a little bit harsh on him but we have to make sure we look after ourselves and our players here.
‘He did go round saying goodbye, although I am not sure where we take it from here.
‘Obviously I will contact the Millwall people and see what is happening.
‘He hasn’t said he is leaving, as such, what he said was he would rather be somewhere where he is going to play and if he’s not going to play down here he would rather be close to his family.
‘If Millwall call him back or if he tells them he wants to go back then that will be the situation we will tackle then.
‘He was a bit upset, of course he was, and I probably would be in his place, I think ultimately he understood the situation I was in – I am the manager of Portsmouth and have to do what is right for this club.
‘It’s the FA Cup this week so whether he would be available for that or not is something we hadn’t tackled.
‘The chances are he would have another two weeks here when not playing.’
