AMERICAN college basketball convert Mason Cox is a chance to make his Collingwood debut in Sunday's NAB Challenge clash against Carlton in Bendigo.

Cox, who was recruited from US college Oklahoma State, has been added to the 29-man squad in place of backman Jack Frost.

The Magpies have also included rebounding defender Adam Oxley with Jesse White pulling out ahead of the game.

Cox has impressed the Magpies with how quickly he has been able to transition to such a foreign game and his sheer want to keep improving.

The 211cm ruckman joins Fremantle's Aaron Sandilands as the tallest player in the League this year and the Pies hope his height, coupled with his excellent vertical jump, can cause some match-up problems this year.

The Pies and Blues will face off at the Queen Elizabeth Oval in Bendigo in front of a sold-out crowd at 4.40pm on Sunday afternoon.
