Falkirk will be without defender Thomas Scobbie due to a recurrence of his pelvic problems.
Scobbie, who pulled out of Scotland's Under 21 squad last week, played through the pain barrier for much of last season.
He had undergone two hernia operations and suffered from tendinitis and osteitis pubis, which causes persistent swelling and pain.
However, Falkirk boss Eddie May concedes that the 21-year-old left-back's welfare comes first and wants to get the problem resolved.
Six weeks out
"Tam Scobbie won't play for six weeks," confirmed May. "It's something he has had over the last few years and he can't do anything about it.
"We'll look after Tam's welfare, I think that's important at a football club. Unfortunately for Tam he can't do anything for six weeks."
Meanwhile, May is crossing his fingers Scott Arfield recovers from an ankle problem which also ruled him out of Scotland's Under 21s.
"Scotty unfortunately had to miss the 21s game," he continued. "We'll wait and see if he comes through Friday's training if he's available."
