West Ham United are sweating over the fitness of Anton Ferdinand after the centre back suffered a hamstring strain.
The 21-year-old sustained the injury in Saturday's 2-1 pre-season friendly defeat to Swedish club IFK Gothenburg.
Ferdinand pulled up with the leg problem after just 25 minutes of the club's latest game on their pre-season tour of Sweden.
Hammers boss Alan Pardew confirmed that Ferdinand will fly back to England to have a scan on his damaged hamstring.
"The down side of the game was not the result, it was the fact we lost Anton," Pardew told Sky Sports News.
"He's strained his hamstring and we'll have to fly him back and see how serious that is.
"It's a precautionary move to get it scanned and see what grade the tear is, but he's done some damage in there.
"We're fingers crossed that it's not too serious.
"We're actually a bit short of defenders on this tour now, so we might have to juggle things around for the third game."
With West Ham's opening Premiership match of the new season at home to London rivals Charlton Athletic on August 19, Pardew is hopeful Ferdinand will be fit to start the new campaign.
"It will be nice to see him if he could make it," Pardew added.
