Veteran Adelaide ruckman Matthew Clarke has nominated for the 2006 NAB AFL pre-season draft and seems set to join his third AFL club next week.Clarke, who announced his retirement at the end of the 2006 season after 247 games in 14 years with first Brisbane and then Adelaide, has been linked to both St Kilda and Collingwood.The 33-year-old is the second recently retired player to change his mind about playing on in 2007, following Brisbane's Mal Michael, but unlike the Lions - who are livid at Michael's decision to join Essendon next year - the Crows have no qualms about Clarke deciding he wants to continue his career at another club in 2007.Just eight clubs will take part in next Tuesday's NAB AFL pre-season draft, which will be followed by the NAB AFL rookie draft, after Adelaide, Brisbane, Fremantle, Geelong, Melbourne, Sydney, West Coast and the Western Bulldogs each submitted a full primary list of 38 players to the AFL.Following a review of each club's total player payments (TPP) estimates for 2007, the AFL Investigations Department determined that the other eight clubs - Carlton, Collingwood, Essendon, Hawthorn, Kangaroos, Port Adelaide, Richmond and St Kilda - were all entitled to at least one draft selection while the Blues have room in their cap for two.The Saints will have just one selection despite the fact they had room on their playing list, but not in their salary cap, for three selections.Carlton has already agreed to take ex St Kilda ruckman Cain Ackland with pick one while Essendon has agreed to take Michael at pick two.The Lions had sought to prevent Michael from being eligible for the draft after he signed with the Bombers just weeks after announcing his retirement from Brisbane, but the AFL ruled on Friday that Essendon could select the three-time premiership winning full-back."An investigation conducted by AFL Investigations Manager Ken Wood has not found any evidence that either Mal Michael or any other third party had been involved in conduct prejudicial to the draft," AFL football operations manager Adrian Anderson said.With the Bombers claiming Michael at selection two, that leaves the Kangaroos with the first "live" selection at pick three followed by Port Adelaide, Hawthorn, Richmond, St Kilda and Collingwood with the Blues to have their second selection at pick nine.Other players to nominate for the draft on Friday besides Ackland, Clarke and Michael were Chris Bryan (Carlton), Anthony Corrie (Brisbane Lions), Ben Eckermann (Port Adelaide), Tim Hutchison (Kangaroos), Kent Kingsley (Geelong), Tom Lonergan (Geelong) and Brad Murphy (Western Bulldogs).This is in addition to the delisted players that were overlooked in the recent NAB AFL draft, a list that includes Adelaide veteran Ben Hart, ex-Tiger Andrew Kellaway and Collingwood's Cloke brothers - Cameron and Jason.And in what was one of the strongest draft years on record, expect at least some clubs to take a punt on some of the talented youngsters overlooked in November - although most of these players can also be picked up in the rookie draft.But it is Clarke who shapes as the prized catch next Tuesday, with both the Saints and the Magpies in need of an experienced ruckman.While both have distanced themselves from speculation the 33-year-old is in their sights, it would be a major surprise if a player that nominated for the draft just weeks after retiring was not picked up.The Saints will have first chance to grab Clarke at pick seven ahead of Collingwood at pick eight while mystery surrounds the Kangaroos' and Port's intentions.But Hawthorn coach Alastair Clarkson has already signalled the Hawks intention to take a younger player at pick five.Richmond is expected to select ex-Kangaroos and Geelong forward Kingsley at pick six while the Blues are rumoured to be keen on taking Cameron Cloke with their final pick at selection nine.
