Sandilands, a $415k ruck owned by over 46,000 DT coaches, has a minor hamstring strain, while Pavlich, a $361k forward owned by over 56,000 DT coaches, has missed the club's last two matches with a calf injury.
Sandilands' fitness is especially important for DT coaches in the wake of fellow ruckman Dean Cox's 2-3 week injury.
Dockers coach Mark Harvey said on Wednesday, "No question they want to be playing this week [but] we will have to overrule to the expertise of our fitness and medical staff.
"It's whether they get through the training session really.
"We'd like them to be playing. We need them to play, particularly with the younger group, so if we can get them out there we will."
Meanwhile, Harvey did acknowledge $75k rookie defender Clancee Pearce would play this week after good WAFL form.
