Chelsea midfielder Nemanja Matic is set to return after missing last weekend’s win over Manchester City with a calf problem.
Diego Costa and Pedro are fit after being forced off during that match, but Oscar and John Terry miss out.
James Morrison and Gareth McAuley are fitness doubts for West Brom.
The pair have not trained this week because of unspecified injuries and will be assessed, while Saido Berahino remains out as he builds up fitness.
Simon Brotherton: “If Chelsea winning 3-1 away at Manchester City last week was something of a surprise, then the fact West Brom are seventh in the table ahead of the latest round of fixtures is arguably an even bigger one.
“Three wins from the last four games has propelled Albion upwards after they’d claimed only a couple of victories from the opening 10.
“Antonio Conte’s team will take some stopping here, though, as they go for a ninth consecutive league win.
“It would be their longest winning streak in the league since they won nine on the trot in 2007.”
Chelsea head coach Antonio Conte on his side being favourites for the title: “We started as underdogs this season, and I think now it’s very difficult to accept this [being favourites], but it’s normal if you’re playing good football and winning a lot of games.
“This league has taught me that every game is very tough.
“Sunday is the type of game we can find difficult if we don’t put the same concentration, the same focus, that we had in the previous games.”
West Brom head coach Tony Pulis: “Every week there’s a challenge, a new challenge, and thank goodness the players have been up for it and we’ve got the results we’ve got.
“When you play against the likes of Chelsea you’ve got to enjoy those games and work as hard as you can and hope on the day it drops for you.
“But if you’re looking on sliding scales we’re not in their sphere for competing week in, week out.
“The manager’s come in and he’s changed things round and got the players playing the way they can.”
West Brom are on a really good run and I am pleased for Baggies boss Tony Pulis that they are so high in the table.
The Baggies have done it by being disciplined defensively and hard to break down but, even so, I don’t see them getting anything at Stamford Bridge.
