Police are investigating a 'racist message' sent to West Bromwich Albion midfielder Romaine Sawyers during his team's defeat by Manchester City.
Albion have contacted the West Midlands force after Sawyers received the abuse via social media and have pledged to ban the sender for life.
A West Brom statement read: 'Everyone at the club is appalled by the abhorrent message which was sent during Tuesday's Premier League fixture against Manchester City.
'The club has a proud history of confronting all forms of discrimination and will assist the authorities with their inquiries, seeking the toughest available legal punishment, as well as a lifetime ban from The Hawthorns for the individual responsible.
