TWO former Roos and an ex-Cat are in line for AFL recalls just seven months after they were dumped by their respective clubs.

Mitch HibberdDeclan Mountford and Cory Gregson headline a list of 22 hopefuls who will be put through a medical screening ahead of the NAB AFL Mid-Season Rookie Draft on May 27.

Each club could lodge up to three players before Wednesday's deadline for the medical screening, which will be held five days before the draft on May 22.

Other ex-AFL players set for screenings include former Dockers Josh Deluca (Subiaco) and Brady Grey (West Coast WAFL).

Mature-age smokies include NT Thunder's Adam Tipungwuti, Coburg's Lochie Dickson and South Fremantle's Marlion Pickett.

Richmond is the club linked strongest to Pickett, while Collingwood showed interest ahead of last year's NAB AFL Draft.

MID-SEASON DRAFT 50 players who could spark up your list

Club medical staff will be invited to attend the testing day, however clubs have been advised they are unable to complete their own individual tests of players.

With 15 list spots currently available across the competition, it is understood a number of clubs will be more inclined to use the draft for future talent rather than ready-made players.

Clubs with one availability include Adelaide, Carlton, Collingwood, Essendon, Hawthorn, Melbourne, North Melbourne, Port Adelaide, Richmond, Sydney and Western Bulldogs.

Gold Coast and Greater Western Sydney both have two positions open to be filled

It is understood Melbourne has previously tracked Gregson, who has returned to SANFL club Glenelg this year after he was cut following a four-year, 39-game stint.

NAB League players Mitch Riordan (Dandenong Stingrays), Cody Hirst (Eastern Ranges) and Kyle Dunkley (Gippsland Power) fit that description and will receive assessments.

Overlooked at last year's National and Rookie drafts, the trio all impressed in last week's Young Guns series-opener at Trevor Barker Oval.

Dunkley is the son of former Sydney defender Andrew and brother of Western Bulldogs premiership player Josh and is being monitored by Sydney, Carlton, Gold Coast and Richmond.

While only a percentage of players from the 307 nominated for the Mid-Season Rookie Draft will be put through screenings, it doesn't rule out others from being selected.

Peel Thunder small defender Jarvis Pina has been catapulted into the WA Under-18 State squad in recent weeks, with multiple clubs showing interest including Fremantle and Sydney.

Clubs such as Fremantle which don't currently hold a pick in the Mid-Season Rookie Draft could yet open up a spot should they suffer a long-term injury or lose a player to retirement.
