Despite this latest setback, Blues head of football Andrew McKay said the club remained confident Kreuzer would play a big role in the upcoming season.
"It's exceptionally disappointing for Matthew given all the hard work he has put in to get his body back to peak shape, but we're confident he will play the majority of the season," McKay said.
Kreuzer has failed to play a full season since he featured in 23 matches in 2009, his second season.
He has since only put together seasons of 13, 12, 20, 17 and one match last year.
