Pompey will look to build on a dramatic victory at MK Dons when they host Blackburn on Tuesday evening.
But it is the third-placed visitors who are the 6/4 favourites with Sky Bet to collect all three points at Fratton Park.
Rovers triumphed 3-0 when the sides met earlier in the campaign and you can find odds of 28/1 on the Blues gaining revenge with that scoreline.
And those who fancy an entertaining contest might want to take a chance on both teams scoring in a game containing more than 4.5 goals at 13/2.
Please gamble responsibly and remember that odds are subject to change.
