Collingwood has made a raft of changes for its match against Brisbane at the Gabba tomorrow night, with veteran Alan Didak called up to make his first appearance of the 2013 season.Having made an irresistible case for a return with a series of strong performances at VFL level, Didak is one of four inclusions for the clash, joining midfielder Josh Thomas, defender Heath Shaw and debutant Kyle Martin, who has been recognised for his VFL form with an elevation to the senior list.While Martin firmly catapulted into selection consideration following his six-goal effort against Essendon in the VFL last week, the 22-year old has undoubtedly affirmed himself as one of the most consistent performers in Dale Tapping’s side and currently sits second on the VFL goal kicking table with 21.Averaging 33 disposals and nine tackles in his last three outings for the VFL Magpies, Martin’s defensive intensity and ability to secure the hard ball has seen him lauded as an AFL player-in-waiting, a prophecy he will be able to realise in the Lions’ den.Director of Football Geoff Walsh described Martin’s elevation to the senior list as due reward for his influential displays in the VFL.“Kyle’s been elevated on the back of some consistent and really strong performances in the VFL,” Walsh said.“Arguably he has been our most consistent player this season. His form in the midfield has been outstanding, he’s also been able to kick goals each week as evidenced by him sitting second on the VFL goal kicking table.“To date, he’s played a pretty impressive season. Alex Fasolo’s injury has opened up an opportunity for Kyle to step up as a long term injury replacement. It’s the old story; someone else’s misfortune creates opportunities for others. In Kyle’s case, it’s well deserved.”Shaw meanwhile returns after overcoming a lower back complaint which saw him sidelined for a fortnight, while Thomas has earned an immediate recall after once again demonstrating his class in the VFL.The incoming quartet replaces Martin Clarke, Jarrod Witts, Sam Dwyer and Jordan Russell, with the latter two players missing out through injury.“Jordy’s ankle hasn’t come up from last week. He tried to come back on against the Swans, but that wasn’t fruitful in itself, while Sammy has a bit of groin soreness,” Walsh said.“He has struggled with it which is contrary to his form, which has been strong, but has suffered a few issues with it during the week, so we just decided to give him a spell in the hope he overcomes it.”Nathan Brown, Ben Reid, Harry O’BrienHeath Shaw, Nick Maxwell, Marley WilliamsSteele Sidebottom, Dane Swan, Luke BallJamie Elliott, Quinten Lynch, Brent MacafferBen Kennedy, Travis Cloke, Alan DidakDarren Jolly, Scott Pendlebury, Jarryd BlairAndrew Krakouer, Josh Thomas, Kyle Martin, Paul SeedsmanMarty Clarke, Jarrod Witts, Ben SinclairDidak, Martin, Shaw, J.ThomasDwyer (groin), Russell (ankle), Clarke, Witts (omitted)Kyle Martin (22, Noble Park/Frankston)
