West Brom manager Tony Pulis has voiced his concern over Chris Brunt’s knee injury.
Brunt is due to have a scan on Sunday to discover the extent of the problem.
The Northern Ireland international was carried off just before half-time after landing awkwardly in an innocuous-looking tussle with Wilfried Zaha.
“He’s done something to the knee joint. We’re obviously hoping it’s not serious because we need Brunty in the team. He gives us balance on that side,” Pulis said.
“Without Brunty, (James) Morrison and (Jonny) Evans, they’re three big players for us and they make us play. Any bottom 12, 13, 14 teams in this league need their best players to play week in, week out to be successful.”
West Brom fans had shown their appreciation for the 31-year-old before and during the game a week after he was hit in the face by a coin thrown by a Baggies fan following the FA Cup loss to Reading.
Pulis was full of praise for the reaction of the fans, who displayed a banner saying: “Brunty: One of us” as the teams walked out.
Pulis said: “The response, the letters and everything we’ve had coming through the door from our supporters has been absolutely fantastic.
“It’s a very famous club, it’s got tremendous tradition, and I think it really shook a lot of supporters. There was a definite coming together today of let’s show everybody that we are what we are - a good club with good support.
“Like everybody else they’ll have a moan and a groan if things are not going well but we’re not a club that condone people throwing stuff, especially at their own, and I thought they were wonderful today.”
