If you made a half-time snack or put the kettle on, you might have missed the game’s big moment on iFollow.
The second period at Wigan’s DW Stadium was just 36 seconds old when Andy Cannon lashed the ball into the net.
It was a superb introduction for the livewire midfielder, who had been brought on in place of Michael Jacobs.
And the goal proved enough to extend Pompey’s winning run under Danny Cowley to four successive games.
Cannon said: “When I was sitting on the bench, I said to everyone: ‘If I come on, then I’ll wobble one top bins!’
“I was laughing with them all about it and then ended up doing just that – so it is a bit of a funny one.
"When I was sitting on the bench, I said to everyone: ‘If I come on, then I’ll wobble one top bins!’"
“I knew I was coming on and was speaking to the manager at the end of the first half. I asked him when the whistle blew and he told me that was still the case.
“Running with the ball, I just thought that I might as well have a pop and fortunately it hit the back of the net.
“It was tough and a bit of a different game to what we’ve seen in the past few weeks. You need a moment and thankfully we got it.”
Victory saw the Blues climb one place to fourth in the League One standings with eight fixtures remaining.
Cannon said: “Back at Christmas we were hoping to finish in the automatic places, but now we’re just taking it one game at a time.
“Four wins on the bounce is good for the confidence, though, and hopefully we can have a good run-in.”
