EMERGING Carlton star Charlie Curnow could be available for the Blues' clash with Sydney next week despite sitting out three quarters of the match against Port Adelaide.

The 22-year-old was chasing the ball alongside Port Adelaide defender Dan Houston on the centre wing before his right knee appeared to give way.

He performed several run-throughs on the boundary line during the second quarter before donning a jacket and taking his place on the bench.

Blues coach Brendon Bolton told reporters after the game that Curnow had "jarred" and "twisted" his knee and was a chance of returning to the field.

"Debating whether he'd come on again but we didn't want to take that risk with someone like that," Bolton said.

"We are really hopeful it's nothing really significant and he's right next week but we need to get it scanned and find out.

"It's a contact sport, it's a brutal game and that's what happens."

Marc Murphy also sat out the second quarter after landing heavily following a marking contest with Sam Powell-Pepper and Zak Butters near the boundary line as the Blues brought the ball out of defence.

He returned to play in the second half but while he and Curnow were undergoing tests, Port kicked 4.3 to 0.2 to open up a decisive 19-point lead at half-time.

Bolton said that wasn't the cause of their poor second quarter.

"It didn't help but we'll never blame that, you've got to go and endure. In that time I think we needed to try and control the ball a little bit more while we were down on rotations and we need to learn to adapt to that quicker," he said.

"The uncontested marks for us were quite low in that quarter so that's about being able to adjust to a scenario so that's something we've got to work through."

Bolton said the players were "filthy" with their final term.

"Game on at three-quarter time, we've been right in it so we know we are good enough against opposition. We've got to do the basics for longer, particularly in the last quarter – I thought they won the territory battle."

Bolton and some of the players will return to Adelaide Oval on Sunday to watch the AFLW Grand Final between the Blues and Crows.

"We're right in behind Harf (coach Daniel Harford) and Bri (Davey) and the girls. They've done a great job from where they were last year within a belief to turn it around, I think it's been fantastic for our footy club."
