Sydney Roosters superstar No.1 James Tedesco refuses to wear long studs on his boots for fear of suffering a serious knee injury.

Tedesco will never forget his NRL debut in 2012 when he ruptured his ACL, and made a point of steering clear of lengthy studs that gripped deep into the ground.

Arguably the game's best fullback was spotted slipping over several times against Cronulla in his first finals game – he has often hit the deck when changing direction at full speed all season – but will not tinker with his boots for better grip.

He looked out and admired the surface at Allianz Stadium this week, but knows the cool evening will almost guarantee a dewy deck against South Sydney on Saturday night.
