Key Bulldogs pair Liam Picken and Stewart Crameri are under the pump trying to prove their fitness ahead of tomorrow's Good Friday clash.
Coach Luke Beveridge says the duo, suffering concussion and a hip complaint respectively, are no guarantees for the Kangaroos game.
"(Liam) seems to be fine, (but) we'll cognistat test him today, which is the test you do to make sure the player is ok to go and play and perform," Beveridge said on Thursday.
"Even when players have passed that test, there's no guarantee they'll be back to their best straight away, but as long as he gets clearance from our doctors, he'll definitely play.
"Whether or not (Crameri) gets the tick off by the medicos is going to be a late call."
