Pompey will look to cause an Emirates FA Cup upset when they visit Loftus Road to take on QPR this evening.
A replay is required following a 1-1 draw on the south coast 10 days ago, with a Joel Lynch own-goal cancelled out by Nahki Wells.
The prize for the victors this evening is a home tie against Premier League opposition in Watford in the fifth round.
Pompey have not got that far since 2010 and they went on to reach the final – going down to Chelsea – that season.
Their opponents currently sit 14th in the Championship table and are eight points adrift of the play-off places.
But since beating Leeds in the third round, Steve McClaren’s side have failed to secure a league victory.
The Blues were beaten 2-0 on their last visit to Rangers back in February 2011, with the hosts going on to claim the title.
This is the first time QPR have cleared the first hurdle since 2013 and they have not made the fifth round for 22 years.
Pompey are without Dion Donohue (shin), Luke McGee (wrist) and Jack Whatmough (knee), but Bryn Morris has recovered from an ankle problem.
Omar Bogle, Lloyd Isgrove and James Vaughan cannot play as they were not registered for the initial tie, while Andy Cannon and Viv Solomon-Otabor are both cup-tied.
Ronan Curtis is suspended after collecting two FA Cup bookings, but Tom Naylor’s two-match ban only covers league matches.
QPR are missing Geoff Cameron (ankle) and Angel Rangel (thigh), while Tomer Hemed (hernia) could be fit enough for a place on the bench.
