Gary Borrowdale is an injury doubt for Barnet's trip to Bristol Rovers at the weekend.
The full-back, who is on loan at Underhill from QPR, suffered a groin injury during Saturday's FA Cup win over Southport.
The Bees were already missing a host of players through injury including Daniel Leach, Anwar Uddin, Izale McLeod, Steve Kabba and Ricky Holmes.
"We were really down to the bare bones," said manager Lawrie Sanchez.
Meanwhile, Barnet's Johnstone's Paint Trophy Area semi-final against Brentford at Underhill has been arranged for Tuesday, December 6.
