Jonny Evans has regained full fitness after missing five games through a calf injury and is in contention to start for West Brom against West Ham.
The Northern Irish defender has been absent for just over a month after suffering the problem during the win over Hull and provides Tony Pulis a boost ahead of Saturday's trip to the London Stadium.
Craig Dawson has been accomplished in stepping across to central defence in that time but Pulis now has the option to return to him to right-back.
West Brom also welcome back Claudio Yacob after the midfielder missed the win over Stoke through sever stomach pains.
