He did the injury in warm up.
You could see him grab his hamstring then go over to THE KING, who promptly sent him down the tunnel for treatment.
He did well then to do 10 mins in the match proper, but was unable to run and was merely acting as a bit of a defensive blocker.
Hindsight is a wonderful thing but to think we have let Emmitt, Johnson and Hargreaves go, who while not having the rep of Perry would have contributed far more and collectively probably not cost as much as Perry.
I just hope he can get himself fit and start to string games together so we can see the player that was good enough to play for the Kangaroos.
