Swansea City must wait to discover the extent of the damage after Wilfried Bony limped off at Everton.
The Swans striker was replaced by Tammy Abraham just five minutes into tonight’s 3-1 loss at Goodison Park after suffering a hamstring injury in the opening seconds of the game.
Bony has been hindered by muscle problems since returning to the Liberty in August, and losing him for a spell would be a heavy blow – particularly as the Swans are just heading into the busiest spell of the season.
“It was a strange one,” Clement said. “It was only two minutes into the game and I don’t know what action he had done at that point to create the injury.
“He has injured his hamstring but how significant it is we are not sure.
“Hamstring injuries are normally a minimum of seven to 10 days, but we will have to see if it is worse than that.”
Ki Sung-Yueng missed the trip to Everton after suffering a calf injury in training.
The problem is only thought to be minor, however, and the Swans are hopeful that he will be fit to face Crystal Palace on Saturday.
