Luke Varney apologised to his Pompey team-mates for his Hull dismissal.
Jason Pearce revealed the attacker said sorry to his team-mates for being sent off for a challenge on James Chester in Saturday’s 1-0 defeat.
Varney received his marching orders with 12 minutes left at the KC Stadium.
The debate raged about whether the former Blackpool should have gone afterwards.
Pompey were insistent it was not a red-card tackle from Varney.
But Pearce explained the player was left floored by the manner in which the dismissal killed hopes of a Pompey fightback.
He said: ‘Luke’s devastated.
‘I told him we knew he would never go in to hurt the guy.
‘He’s disappointed and has said sorry to the lads.
‘We’re going to miss him now unless there’s an appeal.’
Pearce spoke of his frustration at the performance Pompey produced in the Hull loss.
The result made it two away defeats on the bounce for the Blues – but the performance was a world away from the one put in at West Ham.
The defender struggled to put his finger on why his team were not at the races.
But he knows displays like the one Pompey came up with for long parts are not acceptable.
Pearce said: ‘I’m massively disappointed.
‘We knew we had to come here after West Ham and put in the same kind of performance.
‘But we’ve come here and the performance wasn’t good enough in the first-half.
‘The second-half was better, but we’re disappointed.
‘We need to look at the game and see why it happened.
‘Personally, I was really up for the game and was no different.
‘I can’t speak for the other lads but I’m sure they prepared for the game as they normally do.
‘We conceded the goal from distance. They had other chances but so did we.
‘They had more possession but there were chances at either end.
‘But our performance just wasn’t good enough.’
