Hawthorn forward Jon Patton has broken down in tears on the bench after suffering what looks like another leg injury.

Diving for the ball early in the game against Collingwood, Patton suffered a leg injury that saw him ruled out for the game.

The former number one draft pick was in tears on the bench, distraught after years of bad luck.

He has torn his ACL on three occasions and missed the last two weeks with a freak burn on his foot.

Hawthorn GM Graham Wright has confirmed it is a hamstring injury. Wright added he doesn't believe the injury is too bad.
