Reading striker Kevin Doyle will be out for a maximum of four weeks with a hamstring injury.
Doyle's goals have helped Reading move into the top half of the table
The 23-year-old, who has scored 10 goals this season, suffered the injury after 38 minutes of the 1-1 draw with Everton on Sunday.
"We've had him scanned and it's better than we thought," Royals boss Steve Coppell told the club website. "He'll be out for four weeks at the most."
Meanwhile, skipper Graeme Murty is close to a first-team return.
The defender has missed the last three games with a groin problem.
Club physio Jon Fearn said: "He is looking a lot better, and we're hoping he'll be back soon.
"He wasn't quite 100% for the Everton game but the extra few days will take him up a level."
