Carlton forward Matthew Owies suffered a left hamstring injury against the GWS Giants on Saturday afternoon, resulting in him being substituted out of the contest.
Owies, who kicked two goals in the first quarter, making a noticeable impact on the game before succumbing to injury, was replaced by wingman Lochie O'Brien.
The Blues may be under additional injury duress in the form of Blake Acres, whose shoulder appeared hampered in the first quarter. However, he was able to play on after quarter-time.
In any case, Acres was unable to be substituted after Carlton used its sub on Owies.
Defender Mitch McGovern also suffered a leg knock in the second quarter, however, he didn't appear too bothered by it, staying on the field.
The Blues are looking to stay undefeated in 2023 at Giants Stadium on Saturday.
