Brisbane is keeping a close eye on Casey Voss.

Casey, the son of Lions legend Michael, could join the club under the father-son rule, and coach Chris Fagan has taken notice.

“It’d be no surprise to you he’s quite a natural footballer,” Fagan told Sunday Sport.

“We’ve had him up a few times over the last 18 months.

“We’ve been pretty impressed with what he’s been able to do in the NEAFL and the way that he’s fit in with the group.”
