The Baggies have been carrying several knocks for a number of weeks – although Pulis has kept the identity of the players a secret.
Callum McManaman has fully recovered from his foot injury, though, with Saido Berahino and Brown Ideye pushing to start after being named on the bench in last week’s 1-1 draw at Newcastle.
Chelsea striker Diego Costa could return from his hamstring problem for Monday’s match but the Premier League winners are without a number of players.
Goalkeeper Petr Cech (calf) is a doubt and more likely to return for the final game of the season at home to Sunderland but defender Kurt Zouma is out for the rest of the campaign with a knee injury sustained against Liverpool.
Ramires (kidney) and Oscar (thigh) are also out for the season, with young players like Ruben Loftus-Cheek and Isaiah Brown, once of West Brom’s academy, likely to feature.
