Star Fremantle duo, Nat Fyfe and Aaron Sandilands reportedly remain in doubt for the Dockers' clash with Collingwood at Domain Stadium this afternoon.
SEN Radio reports the pair, who were both named in Fremantle's 22, may be late withdrawals from the match.
Fyfe pulled up sore from the side's 100-point loss to Adelaide, while Sandilands missed last week's clash with a hamstring injury.
He was named to make his return, however, back-up ruckman, Jon Griffin was held out of the WAFL game yesterday to be ready for a possible late call-up.
