Swansea City Striker Wilfried Bony faces a spell on the sidelines after picking up a hamstring injury in the 3-1 defeat by Everton on Monday, manager Paul Clement said.
Bony, Swansea's only scorer in the last seven games, limped off after four minutes and was replaced by on-loan Chelsea striker Tammy Abraham.
Swansea are rooted to the bottom of the table with 12 points and have scored 10 goals in 18 games and Bony's absence is a blow ahead of Saturday's clash with 14th-placed Crystal Palace at the Liberty Stadium.
'Hamstring injuries are normally a minimum of seven to 10 days, but we will have to see if it is worse than that,' Clement told the club's website.
