In another pre-season blow for Carlton, ruckman Matthew Kreuzer has undergone surgery on his knee.

The club remains confident Kreuzer will be ready for Round 1, with the procedure being a knee cleanout, according to AFL.com.au’s Mitch Cleary.

Carlton Director of High Performance Andrew Russell broke down the injury this morning.

“Matthew Kreuzer had minor surgery on his knee this week,” he told the Carlton website.

“We don’t expect it to be a major interruption and we’re really confident he’s going to get back to doing some game play late in the pre-season and then be ready for Round 1.

“We’re fortunate that he’s had an excellent preparation to this point and hasn’t missed a beat at all so we expect him to be in very good shape at the start of the season.”

Meanwhile, the Blues expect Mitch McGovern and Will Setterfield to return to full training in the next few weeks.

Darcy Lang however seemingly won’t be ready for round one as he battles a foot injury.
