West Brom midfielder Chris Brunt has been ruled out for two to three weeks with a calf strain sustained at Preston on Saturday.
The 24-year-old was making only his second appearance since returning from a knee injury but limped off on the hour mark at Deepdale nursing a tight calf.
Scans have now revealed the extent of the injury, and although he will miss Northern Ireland's final World Cup qualifier against the Czech Republic next Wednesday, the international break means his absence for Albion will be limited.
Brunt will be a major doubt for next Saturday's home clash against Reading but could come into contention for the game against Swansea on October 20 or the trip to Coventry four days later.
