The Cottagers' full-back suffered the blow during his side's disappointing 2-1 defeat to local rivals QPR, a loss that handed Harry Redknapp's side their first Premier League win
Fulham defender Sascha Riether has travelled to Germany to be assessed by a specialist after the damaging his hamstring during Saturday’s defeat to QPR, manager Martin Jol has revealed.
The 29-year-old, who is currently on loan at Craven Cottage from Cologne, had been an ever-present for the Cottagers this season but had to be substituted at half-time.
The Dutchman has seen his Fulham squad severely hampered by hamstring injuries of late, with Kieran Richardson, Alex Kacaniklic and Bryan Ruiz all having been struck down - with the latter being ruled out until the New Year.
"We have to assess it," Jol told reporters post-match.
"The doctor came in and said he couldn't carry on so I had to change it."
Rither's half-time replacement Stephen Kelly is now expected to deputise during the German’s absence.
Following another defeat away from home, Fulham have won just one of their last nine Premier League outings and currently lie 13th in the table, just five points above the drop zone.
