The contrast in fortunes since Palace last visited the Hawthorns 10 games ago has been huge. After guiding his Baggies side to a 2-0 victory at the start of November, an alarming dip in form saw Steve Clarke sacked as they failed to win any of their next six games.
As the search continues for a new manager, Clarke's former assistant Keith Downing has taking over the reigns for their last four fixtures and remains unbeaten. Three successive festive draws were followed by a New Year's Day victory over Newcastle United thanks to a late Saido Beharino penalty as the Baggies begin to haul themselves away from the drop-zone.
It remains unclear how much priority either side will give to a cup run whilst languishing in the lower reaches of the Premier League, but West Brom have exited the competition twice at the first hurdle in the past three seasons since returning to the top flight in 2010.
West Brom: Downing has almost his whole squad to choose from, with the only worries concerning striker Victor Anichebe who missed the midweek win over Newcastle with a groin problem and Billy Jones who was subbed at half-time with a cut to his face.
Summer signings Matej Vydra, Goran Popov, Diego Lugano and Scott Sinclair have all featured sporadically this season and could get some useful game time under their belts ahead of the second half of the season.
Palace: Tony Pulis is likely to rest some players after a busy festive period, but will definitely be without long-term injury absentees Glenn Murray, Jack Hunt, Adlene Guedioura, Jerome Thomas and Paddy McCarthy.
Kagisho Dikgacoi limped off against Norwich City on Wednesday so is unlikely to be risked but Stuart O'Keefe is fit again after a hamstring strain.
