HAWTHORN youngster James Cousins will likely miss the rest of the season after hurting his shoulder in Box Hill's loss to Williamstown on Sunday.

Cousins suffered the injury early stages of the match, but bravely played on to collect 24 touches and kick a goal.

He will require surgery on the shoulder and is unlikely to play again this year.

"Cuz managed to play out the rest of the game, which is a testament to his toughness and determination to help the team," general manager of football operations Jason Burt said.

"Unfortunately, he’s going to have surgery on that shoulder, and he will miss a chunk of the season.

"He’s a great kid and a promising footballer, so we want to make sure his body is 100 per cent right going forward."

The 19-year-old, who was pick No.46 in last year's rookie draft, has impressed in his first season at the Hawks.

He made his debut in round 10, averaging 13 touches and four tackles across his three senior appearances.
