CARLTON forward Levi Casboult is likely to stay at the Blues after attracting limited interest during the NAB AFL Trade Period.

The 28-year-old – who is contracted until the end of next year – was put on the trade table after playing just 10 games this season.

Blues list manager Stephen Silvagni told NAB AFL Trade Radio that he expected Casboult would remain with the club.

"I would think so at the minute," Silvagni said.

"We haven't had too many approaches from clubs.

"At the minute, it looks more likely that he'll be here than play at another club."

Silvagni said the 201cm Casboult could also provide support in the ruck to veteran big man Matthew Kreuzer.

The Blues bolstered their forward line stocks on Wednesday when they secured Adelaide high flyer Mitch McGovern.

Meanwhile, the Blues face a battle to retain Irish defender Ciaran Byrne, who has returned to Ireland during the off-season.

"It's looking a little bit grim at the minute, but we're still trying to get him back here if we can," Silvagni said.

"He gets terribly homesick when he gets home and he finds it hard to come back."
