A Fremantle Dockers horror weekend with a disastrous injury crisis could get even worse with fears key defender Alex Pearce may be a latest casualty after further damage to his thumb.

Dockers management is already bracing for confirmation that star playmakers Nathan Fyfe and Aaron Sandilands will be sidelined for up to a month with injuries they suffered in Sunday’s nightmare home clash against battlers Brisbane.

Sandilands, 35, suffered a nasty right calf strain just minutes before bouncedown and was a late withdrawal.

Superstar Fyfe pulled his hamstring midway through the second term, with the Dockers already four goals down.
