Hayden Mullins is edging close to a Pompey exit.
The Pompey midfielder is in talks with Reading over a move to the Blues’ Championship rivals.
He is looking increasingly likely to follow Stephen Henderson out of the door, with the keeper set to join West Ham.
Michael Appleton admitted Mullins was left out of the squad at Brighton today with his manager concerned that his mind would not be on the game.
He said: ‘I left Hayden out because there’s an opportunity for him to speak to a club over the weekend.
‘I didn’t want him getting too mixed up with what was going on off the field, so I gave him a breather.
‘Stephen is at West Ham for a medical. It’s a loan with a view to a permanent.’
Appleton was left frustrated by the 2-0 defeat at Brighton - and though his men warranted a return from the game.
He said: ‘It looked like a 0-0 draw all the way.’
