Carlton forward Charlie Curnow is optimistic this morning, despite injuring his knee in the Blues'16-point loss against the Power.

Curnow was chasing the ball in defence and immediately clutched his knee as he went to ground.

But the forward says at this stage, he has been cleared of an ACL injury.

“That’s all cleared, I’m pretty sure,” Curnow told Nine News.

“It (the knee) feels pretty good.

“Just pulled up a bit sore last night.

“After we strapped it up, we just made the decision to not really risk it.

“Just had the scan then so have to wait and see for the results.”

The Blues will aim to record their first win of the season against the Swans on Saturday at Marvel Stadium.
