Luton Town boss John Still believes striker Paul Benson could be back from his broken leg in six weeks.
The 35-year-old scored in the 19th minute of last Saturday's 3-0 win over Mansfield, but was injured and taken off eight minutes later.
"Any fracture or break is disappointing. But if he had to have a fracture, it's in the right place," Still told BBC Three Counties Radio.
"If all went well with him, I think we're looking at six weeks."
An initial assessment of Benson's x-rays suggested he had escaped serious injury, but he was later diagnosed with a leg break.
Injuries have prevented the former Swindon striker, who scored 18 times for the Hatters last season, from having a sustained run of first-team football this term.
"For Paul it's disappointing, because I think he was getting back to proper fitness," said Still.
The Luton boss is now considering whether to bring in a replacement for Benson during the January transfer window.
"We know the type we want and if that sort of type became available, we would do something," he added.
"But I'm not bashing the door down for it."
