West Bromwich Albion defender Billy Jones has emerged as an injury doubt for Tuesday's Premier League encounter with Chelsea at The Hawthorns.
The 26-year-old received a knock to his knee during the Baggies' 3-1 defeat at Crystal Palace on Saturday.
Jones will join Nicolas Anelka and Stephane Sessegnon on the sidelines if he is ruled out, while Jonas Olsson could return to action following a hamstring problem.
West Brom head into the match one point adrift of safety in the table.
