PRIME Carlton prospects Harry McKay and Sam Petrevski-Seton remain on modified programs, only weeks out from the club's opening pre-season matches.

They were two of a number of Blues, including Alex Silvagni, Sam Rowe and recruits Aaron Mullett, Darcy Lang and Jarrod Garlett, not to compete in match simulation at Craigieburn on Wednesday. understands two-game key forward McKay, the No.10 pick in the 2015 NAB AFL Draft, is battling a toe injury. 

Petrevski-Seton made 20 appearances in his debut season last year – scoring a NAB AFL Rising Star nomination in round seven – despite a quad injury preventing him from playing in the pre-season. 

The silky 19-year-old, Carlton's first selection and the No.6 choice overall two years ago, trained away from the main group in recent weeks and instead focused on running drills. 

Mullett completed his work on a separate oval on Wednesday, while Garlett practised his goalkicking during breaks in the match simulation.

Rowe's recovery from a major knee injury suffered in May last year against Fremantle remains on track and he is aiming to return in the early rounds of the 2018 season. 

The Blues trained on Princes Park's back ovals and at Craigieburn's Highgate Recreation Reserve, home of TAC Cup club Calder Cannons, this summer as Ikon Park was resurfaced. 

The first match of the AFLW season between Carlton and Collingwood will be held at Ikon Park on Friday night and the Blues will be back training there from next week.
