Adelaide great Taylor Walker has failed to overturn his one-match suspension for rough conduct at the AFL tribunal.
Walker was offered a one-game ban for pushing Geelong's Connor O'Sullivan into Adelaide captain Jordan Dawson in a marking contest in the Crows' one-point win last Thursday night.
The former captain's action was deemed careless conduct, with medium impact and high contact, by match review officer Michael Christian.
Adelaide's all-time leading goalkicker challenged the suspension at a tribunal hearing on Monday night.
Walker didn't speak at the hearing but, through his counsel Andrew Culshaw, argued the charge should not have been graded as high contact.
"What happened here was an attempt to put body on Connor O'Sullivan to keep him away ... to allow Jordan Dawson to mark," Culshaw told the tribunal.
