Adelaide forward Darcy Fogarty will not play on Sunday due to a shoulder knock sustained in training.

Crows Head of Science and Medicine Steve Saunders said the 20-year-old would be monitored during the week to determine his availability for Round Five.

"Darcy suffered a heavy contusion to the left shoulder late in training on Friday," Saunders said.

"Scans have shown extensive bruising of soft tissue and bone."

Elliott Himmelberg will replace Fogarty in Adelaide's final 22.

Myles Poholke, Will Hamill, Ben Crocker and Himmelberg will start the game on the interchange.

First bounce is at 1.05pm (AEST).

The match will be broadcast live on Fox Footy and Channel 7 in Adelaide.
