The club narrowly missed out on a trip to Wembley after being held by a late goal against Manchester United at Old Trafford before losing 2-1 in the replay at Upton Park earlier this month.
And the hosts will need to make special arrangements for big striker Carroll, who has hit some of the best form of his career in the last couple of months.
Carroll's consistent form for the Hammers has seen him net six goals in as many games including a superb hat-trick against Arsenal and a fine goal against Watford last time out.
His form has also seen him enter the Premier League's top 10 Power Rankings for the first time this season at number four, as reported by Sky Sports.
Andy usually bags against the Baggies
The Power Rankings methodology reflects a player's performance over the previous five weeks, with each preceding week worth fewer points. This means the Power Rankings reflect the in-form players of the moment.
Carroll has notched up 12,467 points and trails leader Sergio Aguero, Alexis Sanchez and Harry Kane.
The Baggies need little reminder of Carroll's qualities, though. The former Newcastle United star has a habit of scoring against West Brom and the hosts will need to be on top of their game to keep him under wraps come Saturday afternoon.
