Billy Jones doubtful for West Bromwich Albion

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.
