Fresh injuries to test Force depth

Force head coach Michael Foley hopes injuries stemming from his side's loss to the Crusaders won't be too serious heading into their bye week.

Jordan Taufua's late score snatched victory away from the Force on Friday in Perth.

Counted the wounded, Alby Mathewson was a late withdrawal before kick-off due to illness, while Ian Prior (knee), Pek Cowan (arm) and Nathan Charles (dislocated shoulder) will all be monitored.

"Pek's going to go off for an x-ray. Ian will have to get a medical exam but we're quite hopeful that's not too serious and Nathan is probably the most concerning of the lot but we'll know a lot more in the next 24 hours," Foley told AAP.

"We definitely had some disruptions, but I just think the difference in the squad this year is that we just don't flinch at those things or overthink about those things.

"We just expect the guys to step in and do the job, and guys have really performed when we've asked them to."

Friday's loss was the fifth in a row for the Force, and they could move to the bottom of the Australian Conference depending on the Reds' result with the Highlanders on Saturday.
