Adelaide are understood to have decided against nominating highly-rated draft prospect Isaac Keeler as a Next Generation Academy option for this month's National Draft.

Keeler firms as a likely top-40 selection at the draft, meaning the Crows will be unable to match a bid for the North Adelaide tall should a rival club call his name before the cut-off.

The Crows are already set to see a number of their draft selections absorbed in a looming bid for father-son prospect Max Michalanney, who the club confirmed as a draft recruit last month.

While Michalanney's name was officially listed before last Wednesday's deadline for father-son and Academy nominations, have reported that Keeler was not included.

The forward-ruck hybrid is among a handful of NGA prospects that are set to land in the opening two to three rounds of the draft and be out of reach to the AFL clubs they are tied to.

St Kilda's Academy gun Cameron Mackenzie firms as a potential top 10 selection, while Essendon will sweat on rivals moving on Anthony Munkara before Pick 40.

Keeler is sure to gain interest from the likes of Hawthorn, Collingwood and GWS, who will be assessing key position options at the draft.

The talented teenager played 15 matches for North Adelaide's U18s side this season, booting 19 goals and averaging 17.9 disposals, 4.2 marks, 3.3 clearances and 3.1 inside 50s for the Roosters.

The athletic South Augusta product was also a prominent figure for South Australia at the National Championships this year.

With emerging tall Riley Thilthorpe still in the early years of his development at West Lakes after joining the club as the second overall selection from the 2020 National Draft, the needs for Keeler at the Crows are limited.

Michalanney will add to the club's defensive stocks from next season, while Adelaide are likely to gain at least one other player through the draft in the later rounds.

Their hand of Picks 46, 56 and 59 are sure to shuffle throughout the draft, with the bid for Michalanney to impact their first few selections while their selections are sure to move up the order after a number of early father-son bids.

The 2022 National Draft is set to take place across two nights, commencing on Monday, November 28.
