Hibs boss Terry Butcher has revealed that striker Paul Heffernan is facing six weeks on the sidelines.
The 31-year-old pulled up with a thigh strain only five minutes into Saturday's 0-0 draw with St Mirren in Paisley.
Butcher has now revealed that he could lose the former Killie man for as much as six weeks.
"It could be three to six weeks; we're not too sure yet; we're waiting on the results of a scan," Butcher told the club's official website.
"It's unlucky for Paul but it gives other people, like James Collins, a chance to get into the team."
