A host of players will be looking to prove their fitness ahead of Round 20. 

Tim O'Brien was a late withdrawal ahead of the side's game against Brisbane last week.

O'Brien was dealing with calf soreness in the lead-up to the Lions game and was unable to recover in time.

But O'Brien joins Harry Morrison, Dylan Moore and Jack Scrimshaw as those looking to be available to play this weekend.

Scrimshaw has not played since the Round 10 game against Port Adelaide.
