The news that Johnathon Thurston suffered a knee injury at training has sent shudders through Maroons supporters.

Thurston took a couple of heavy knocks at training just days out from the crucial Game Two Origin encounter in Sydney and spent the rest of the session icing the knee.

Thurstons Cowboys teammate Gavin Cooper (pictured), who will play just his second Origin game on Wednesday night, says the injury  isn’t serious and the team has no doubt the Qld champ will be able to withstand the pressure that will be coming his way courtesy of the giant Blues forwards on Wednesday night.
