CARLTON star Bryce Gibbs is confident a thumb injury won't rule him out of Saturday's clash with Sydney at the MCG.

Gibbs injured his left thumb during the Blues' 90-point mauling at the hands of Port Adelaide on Friday night.

The 28-year-old went in for scans on Sunday morning, but wasn't concerned the injury might sideline him for the encounter with the winless Swans.

"I wouldn't have thought so," Gibbs told Channel Seven.

"I haven't got the results back yet but I've actually had a similar thing (injury) about five years ago and played through that without any trouble.

"I should be right for next week."

Skipper Marc Murphy had scans on the knee injury suffered against Port Adelaide, but Gibbs was equally confident he would be fit to lead the side next week.

Gibbs has enjoyed a good start to the season, averaging 26 possessions in five games, after his failed attempt to return home to Adelaide during last year's trade period.

It has been speculated the 214-game veteran will ask for a trade to the Crows again at the end of the season, but he wouldn't be drawn on the topic.

"Once the decision came through that a trade couldn't be facilitated I said to myself 'That's it, I'm not going to think about it, I've got to move on'," he said.

"And that's what I've done. I haven't put any thought into the end of the year or next year or the year after that.

"I've still got a couple of years to go on my contract at Carlton and that's purely my focus.

"There is going to be a lot of speculation probably for the rest of my career and that's just something you learn to put up with and deal with.

"I've just got to let my footy do the talking and keep that chatter as quiet as possible."
