North Melbourne can confirm the season is over for Mitchell Hibberd and Ben Jacobs.

Hibberd will require surgery after injuring his shoulder against Port Adelaide on Saturday.

“Mitch was involved in a marking contest in the first quarter and extended his arm over his head in an attempt to spoil the ball,” North doctor Peter Baquie told NMFC.com.au.

“His arm was awkwardly sandwiched between two players. Upon assessing his shoulder on the bench, we immediately ruled him out of action for the remainder of the game and knew the outcome after scans would be unfavourable.”

The 20-year-old will miss the next four to six months.

Jacobs meanwhile had a minor procedure on his foot last week and although he pulled up well, he won’t be risked.
