KEY FORWARD Sam Weideman took to the testing floor on Wednesday as clubs weigh up where to place the imposing goalkicker in their draft orders.

Weideman, who hasn't played since May this year after battling an ankle stress fracture, completed a series of fitness tests under the guidance and supervision of AFL academies high performance manager James Veale.

The 197cm prospect, who is in the mix for Melbourne's pick No.3, ran 3.21 seconds over 20m and recorded a level 12.4 beep test.

The testing was in lieu of those done at the NAB AFL Draft Combine, when Weideman was unable to test as he was still recovering from the long-term injury.

He completed in running tests and also did the agility test in the private session, running 8.69 seconds.

Later in the afternoon, he was also one of 12 prospects to be medically assessed by club doctors and physios at AFL House in their final screening before next Tuesday's draft.

Although Weideman's results were not stunning, more emphasis is likely to have been placed by clubs upon his medical results and the views of their doctors regarding his ankle injury.

Sydney Swans academy midfielder Callum Mills, and possible father-son pick-ups Josh Dunkley and Bailey Rice, also did testing after injuries restricted them at the combine.

Mills, who is tipped to attract a top-five bid on draft night, ran 3.06 seconds for the 20m sprint and 8.14 seconds for the agility test, which would have placed him inside the top five at last month's national screening.

Dunkley also registered a strong agility test with 8.31 seconds, but Rice managed just a level 12.2 beep test.

Rice has nominated St Kilda as his preferred destination over Carlton in the new bidding system, while Dunkley has until Friday to decide whether he will nominate as a father-son to the Swans or enter the open draft.

The testing and medical screenings on Wednesday may play a significant role in determining where Weideman ends up being taken at the draft.

The Demons could add the straight-kicking and strong-marking forward to partner Jesse Hogan, but he has also been linked to Essendon, Gold Coast and Carlton inside the top 10 picks.

Weideman is the grandson of Collingwood legend Murray, who captained the Magpies' 1958 premiership team, and the son of former Pie Mark Weideman.
