Pompey have had an unwanted gap of three weeks since winning at Hull to reach the League One summit.
A combination of Covid-19 and the weather caused the postponements of games against Swindon, Bristol Rovers and Accrington.
It means that the squad have been well-rested ahead of Sunday’s visit to Championship side Bristol City in the Emirates FA Cup.
And Kenny Jackett is relieved to be preparing his side for action again in the third round contest at Ashton Gate.
The Blues boss said: “It was really frustrating to have the Accrington match off because we were all clear in terms of Covid and training hard, but it couldn’t be helped.
“You looked at the weather in that area of the country and there were problems, so it’s one of those things and we’ll now have to go there on a Tuesday night.
“It means the games will be coming thick and fast – starting this weekend – but we’re looking forward to playing again.
"It’s good to have a couple of cup ties to get us going again, although we won’t underestimate the size of the task."
“They’ve trained very well and we’ve had to make sure we keep ticking over – the attitude has been good and that should be reflected in the games coming up.
“Bristol City are an excellent side and have made a positive start to the season, so we’re looking forward to it.
“It’s good to have a couple of cup ties to get us going again, although we won’t underestimate the size of the task.
“We’ll want to hit the ground running and try to get through against an established Championship side.”
Jackett welcomed the recent news that all sides in the EFL are to start receiving twice-weekly Covid-19 tests.
He said: “The PFA have stepped in to ensure the safety of the players and it means we can be more organised around symptoms.
“People pick up different illnesses at this time of year, so you do need to know if it’s Covid and then stop it spreading through your squad.”
