London, England – Fulham midfielder Steve Sidwell is set to 1 draw with West Bromwich.
The 29-year-old already missed time this season after undergoing hernia surgery, and although the former Reading, Chelsea and Aston Villa man completed the full 90 minutes in Wednesday's match, Fulham boss Martin Jol is fearing another extended absence.
"We had an injury to Steve and he will be out for a long time - for four, five or six weeks," Jol told the league's website. "He had a hernia operation as you know and it is almost the same problem.
"He had an operation and now we have to wait, but we fear he needs another operation."
Sidwell has appeared in 14 league games for the Cottagers so far this term and has played in 41 matches in all competitions since joining from Villa in January 2011.
