Crows midfielder Brad Symes will have a knee clean-out today.
Symes has battled knee soreness in recent weeks and the arthroscopy will keep him off the main training track until late January.
“He has just got a little bit of material in the knee which needs cleaning out,” said caretaker football operations manager John Reid.
Senior coach Neil Craig told supporters at Tuesday night’s members information night that Ben Rutten (knee) and Nathan Bock (heel) would start running before Christmas. Nathan van Berlo (back) will be held back until after the break.
