North Melbourne's Jy Simpkin will be free to face Geelong this weekend after successfully challenging his two-match sanction for contact against Brisbane's Allen Christensen in the opening quarter of Sunday's clash with the Lions at Etihad Stadium.

Simpkin was initially handed a two-match ban for making careless contact with high impact to the head.

After just six minutes of deliberating, the jury found Simpkin not guilty of rough conduct, with the Roos arguing Simpkin was contesting the ball, and circumstances outside his control meant he had no other option than to brace.

Simpkin will be available for selection this weekend.
