Sydney captain Callum Mills could be sidelined once again, only this time due to a suspension.

Mills returned to the senior side after an injury-interrupted start to 2025, which followed on a plagued 2024 campaign due to shoulder and soft-tissue issues.

However, on Sunday, the Swans skipper was seen electing to bump Melbourne forward Charlie Spargo, coming off the ground before collecting the latter.

Spargo was subbed out of the game following the incident.

Mills is immediately liable for jumping off the ground and should expect some attention from the MRO.

The MRO will hand down its findings from Sunday's games on Monday.
