Greater Western Sydney's No.1 draft pick Jonathon Patton appears to have overcome an unexpected final injury hurdle ahead of his long-awaited AFL debut.

The 19-year-old key forward is listed to play against Richmond at Sydney Showground Stadium on Saturday after having the start of his senior career delayed by knee surgery in Sweden last January.

Patton sent a scare through observers at training yesterday, as he limped off the ground shortly before the end of the session.

Onlookers initially feared the problem might have been the left knee that was operated on.

He quickly applied an ice pack to his left thigh, but Patton and assistant coach Mark Williams were adamant it was just a minor cork.

Club officials later confirmed that was the case and said Patton would definitely play on Saturday.

It was a tough day for all three of the Giants' key forwards paraded before the media prior to training.

Israel Folau, who has just come back from a hamstring strain, didn't train and coach Kevin Sheedy said the league convert would have a fitness test on Saturday morning.

Sheedy rated Folau's prospects as 80-20.
