Swansea City skipper Angel Rangel could require surgery for an abductor muscle injury and faces a lengthy spell on the sidelines, manager Carlos Carvalhal said.
The defender has played three Premier League games this season and has not featured since the 2-0 defeat by Tottenham Hotspur last month. He joins midfielders Renato Sanches and Leroy Fer apart from striker Wilfried Bony on the injury list.
