Crows midfielder Matt Crouch will have season ending shoulder surgery this week.

The 29-year-old suffered a knock in the first quarter of Saturday's loss to Hawthorn and subsequent scans confirmed a right AC joint injury.

"It's really disappointing for Matt who has been playing some great footy this year," Adelaide High Performance Manager Darren Burgess said.

"Unfortunately, the severity of the injury requires surgery and he will miss the rest of the season.

"But the timing of it means he will begin his rehabilitation straight away and be ready for the start of pre-season."
