Williamstown duo Kallan Dawson and Tom Downie are understood to be on the radar of AFL clubs ahead of Wednesday's Mid-Season Draft.

Downie, a former ruckman for the GWS Giants, has also emerged as a potential candidate at the Mid-Season Draft as rucks are again becoming an in-demand asset.

Last year saw four of the top seven picks select a ruckman, with several sides set to follow the trend in 2022.

Sandringham Dragons tall Max Ramsden, WAFL ruck Brynn Teakle and former Lion Connor Ballenden are also reported to be a chance to land an AFL list spot.

Downie played nine games for Greater Western Sydney across six seasons with the New South Wales club, announcing his retirement in 2017 amid a battle with mental health.

The 29-year-old is averaging 35.6 hit-outs this season in the VFL, and is understood to be gaining interest from Hawthorn, according to 7 News' Tom Browne.

The Hawks have also been linked to Ballenden and Box Hill defender James Blanck ahead of the June 1 draft, with the latter seen as a leading defensive option for AFL clubs.

Like Blanck, Dawson has been touted as a near-certain selection at the draft following an impressive run of form in the VFL, having played eight games this year as an intercepting defender for Williamstown.

Collingwood are reportedly "keen" on Dawson's services as they look to fill the void left by retired veteran Jordan Roughead.

The Magpies could pair Dawson with former Seagulls teammate Charlie Dean at the AIA Centre, with Dean having joined Collingwood through last year's Rookie Draft.

"Collingwood are keen on a defender after Jordan Roughead's retirement," Browne said on Monday night. "The Mid-Season Draft is really the stuff of dreams.

"The Pies are looking at Williamstown's Kallan Dawson, he's a talented defender and full-time sparky.

"That could be a surprise packet."

Collingwood are set to hold two picks at the Mid-Season Draft, their first likely coming at ninth overall, while Hawthorn are poised to have just the one selection at Pick 6.
