Hunter Clark has undergone surgery to repair multiple fractures to his jaw following a courageous contest in last night’s game against Adelaide.

The 22-year-old left the field halfway through the second quarter and was immediately ruled out for the remainder of the game.

“Hunter will likely miss 6-8 weeks, which is hugely disappointing,” Chief Operating Officer Simon Lethlean said.

“He put his body on the line and head over the footy, which are some of the things we love about Hunter’s game, but ultimately he’s come off second best in this instance.”

Clark joins an extensive Saints injury list, with more than 10 players already likely to be unavailable for the club’s next game.
