And his assistant manager has paid tribute to Jackett’s resolve and determination to make Pompey a success this season.
The 59-year-old was present at Fratton Park for the 1-0 defeat - just two days after undergoing surgery to remove a mole from his arm. Jackett was expected to be away from duties for at least a fortnight to recuperate.
His No2, Joe Gallen, admitted what Jackett had been through was worthy of concern, but the Pompey boss is now continuing in his role as normal.
Gallen said: ‘That’s him. He’s back. He’s back in on Monday - and away we go on Tuesday.
‘I did say he’d be back sooner rather than later but he has surprised me.
‘Health is everything. It’s when something happens you think “wow”.
‘We all get caught up in our own worlds and we're concentrating here on winning games.
‘But then something like that happens. Wow.
‘Let’s be honest, it would play on your mind. It would me.
‘But he’s back fit and healthy with the all clear.
‘With Kenny, whatever football club he works for he gives it everything he’s got.
‘His whole time and being is to make Portsmouth successful. That’s what he’s going to do.’
Gallen confirmed Jackett’s surgery went as planned and with no issues in its aftermath.
That should now hopefully leave the path clear for him to take his position in the dugout at Oxford United on Tuesday night.
Gallen added: ‘I did think he’d be back sooner than everyone thought, but this soon? No, but there you go.
‘He looked normal and fine, the operation was a success and that was the main thing.
‘He’s got the all-clear on everything and that’s great news.
‘But he’s back, fit and healthy.’
