Blues ruckman Matthew Kreuzer hopes his latest bout of surgery has fixed his troublesome foot.

Kreuzer went under the knife last week for the second time, after having a similar operation in the off-season on the foot he injured in the Blues' elimination final win against Richmond.

He is expected to miss between 12 and 14 weeks.

"Hopefully it's all fixed now. I had the operation on Friday, so I had a bit of a bone graft and a plate put in," Kreuzer told Fox Footy's On the Couch.

"So hopefully that does the trick now."

Kreuzer's progress has been hampered by a long list of injuries, included an ACL injury in 2010 that required a full knee reconstruction.

Despite some questioning why he was taken with pick No.1 in the 2007 NAB AFL Draft, the Blues' big man said he still has improvement left in his game.

"You can say that, but that's football isn't it? It's a contact sport – you've just got to cop them (injuries) and get back to improving when you do get back out on the field," Kreuzer said.

"You look back and there's always things like the knee or whatever, it's just one of those things that you need to keep improving and I'm still developing my game."
