Dayne Zorko is eying an AFL return, while Keidean Coleman seems unlikely to play in an important early-season fixture against Melbourne on Friday night at the Gabba.

Observing Brisbane's training on Tuesday, AFL Media's Michael Whiting reported that Zorko was set to play in Round 2, having shown progress from a hamstring setback in February.

It would be the 34-year-old's first game since stepping down as captain.

The return of Zorko would come as a handy addition for head coach Chris Fagan after his engine room was belted at stoppage time by Port Adelaide, losing the clearance count by 11 on what became a sorry afternoon.

Meanwhile, Coleman, subbed out after a head knock against Port Adelaide, will be unavailable against the Demons having entered concussion protocols in the aftermath of the collision.

In limited game time, the 22-year-old was one of Brisbane's best performers on an otherwise disappointing day.

Experienced defender Darcy Gardiner could be out longer than expected, after undergoing shoulder surgery in the offseason and recovering slowly from an ankle setback.

Callum Ah Chee also remains sidelined as he deals with a quad strain.
