The pair required emergency medical attention after picking up injures in the weekend game with Southport.
The National League North match ended goalless - and the welfare of the players was on the minds of supporters after, and not the result.
“Sam Muggleton and Terry Galbraith were both taken to Darlington Memorial Hospital for treatment after sustaining injuries during Saturday’s home game with Southport,” the club confirmed.
“Sam has sustained two injuries – a partial fracture of his femur, and knee ligament damage caused by a dislocation. He will be having a further scan on Monday to assess the extent of the damage.
“Tez has suffered a partial concussion, and will be ruled out of Wednesday’s home game against Brackley.
“We’re sure that everyone connected to the club would like to wish both players a speedy recovery.
“We would also like to thank the medical staff for their care and attention during and following both incidents.”
