Swans duo Will Hayward and Jarrad McVeigh are both set for a stint on the sidelines after suffering injuries in Sydney’s round three win over Carlton.
Hayward will miss four weeks after having surgery on his broken jaw.
The forward suffered the injury in a heavy collision with Carlton defender Kade Simpson.
Meanwhile, McVeigh could miss up to two months of action with a quad injury suffered while kicking.
These two outs come at a poor time for the Swans, who will need to attempt to replace Hayward’s goals and McVeigh’s drive off half-back ahead of this week’s clash with bottom-placed Melbourne.
