Dale Finucane has until Saturday to convince the coaching staff is ready to make the trip to Kogarah.
The Storm hard man has been named in the side to return from a broken thumb to take on the top of the table Dragons this Sunday.
However before he boards the plan, he has several boxes still to tick before he is given the final green light.
"(Dale) just needs to show he is comfortable catching the ball, carrying the ball and probably more importantly he can make his tackles," Craig Bellamy said.
"He has done all the right things which is a credit to him and has gone all the steps with our medical staff.
"He had surgery there and had a pin inserted into his thumb. He probably would have played two-three weeks ago if it had of been up to him."
Suliasi Vunivalu (thumb) and Curtis Scott (ankle) remain under similar injury clouds and will also be given until the weekend to prove their fitness.
"We are not playing until Sunday, not sure how much of the session they'll do today," Bellamy said.
"We've got Captain's Run on Saturday so it might be up until then that we give them."
