The Baggies are still sitting pretty in the Premier League - currently seventh - and are priced as 4/5 (1.80) favourites with Paddy Power to overcome the division's bottom-club QPR within the 90 minutes.
The West Midlands side will be extra motivated to beat Rangers after they were left fuming at their West London opponents recent double bid for two members of their squad.
QPR's €6million offer for defender Jonas Olsson and a €2.4m move for striker Peter Odemwingie were blocked by West Brom, and made public, which will ensure the visitors face a hostile reception in this cup clash.
Rangers are starting to see improved results under Redknapp though, and could extend their three-game unbeaten run with a victory here at 7/2 (4.50).
A late goal from Kieron Dyer at Loftus Road gave QPR another crack at the FA Cup cherry with this replay, as the injury-plagued midfielder secured a 1-1 draw.
Backing a stalemate at the end of 90 minutes in this encounter is available at 5/2 (3.50) - and shouldn't be ruled out given QPR followed up their draw with West Brom by holding Tottenham.
But the Baggies have a great recent record against Rangers, remaining unbeaten from their last five meetings in all competitions.
The two clubs have already played out their Premier League fixtures for this season, and both home and away games were won by West Brom.
With the Midlands derby against Aston Villa to come at the weekend, Clarke will demand a much-improved performance from his players, and has stated his desire to witness a good cup run this campaign.
On the other hand, Redknapp's revelation that he is having sleepless nights plotting QPR's survival in the league should mean that he looks at FA Cup success as just an added bonus to their principal aim of staying up this term.
Romelu Lukaku scored twice last time out - as well as striking the woodwork and having a goal disallowed - and the on-loan Chelsea forward is 5/1 (6.0) to bag the first goal again in this game.
With QPR struggling for goals - scoring just three times from six games - Lukaku could continue his good form by adding to his current haul of nine by netting here on home soil.
