Barring injury in Wednesday night�s third State of Origin match Melbourne prop Robbie Kearns and hooker Cameron Smith will slot back into the Storm line-up this week but Robinson is struggling to overcome knee and ankle injuries.
The 27-year-old back-rower�s right leg was injured in the opening minutes of last week�s six-point win over North Queensland.
Robinson hasn�t been named for Sunday�s match and will need to make a rapid recovery this week if he is to play.
�He (Robinson) has a bad ankle sprain that has been responding quite slowly to treatment,� Storm doctor Greg Hickey said.
�He has also suffered a minor medial ligament sprain in his right knee. Neither injury is all that serious but they have certainly slowed his recovery this week.�
Prop Kirk Reynoldson is expected to make a full recovery after being knocked out during last Saturday�s match and as such has been named as Robinson�s replacement in the back-row.
Similarly rookie Dustin Cooper will be monitored throughout the week after suffering concussion in the second half of Saturday night�s match, he is expected to play against Brisbane.
31-year-old Kearns will partner Mitchell Sargent in the front-row while Smith�s return to hooker has forced Nathan Friend and Danny Williams on to a six-man bench with two players to be omitted before Sunday.
Forward utility Glen Turner is eligible to play this week after he entered an early plea for a grade two careless high tackle charge stemming from last week�s match.
