Port Adelaide star Robbie Gray could come under scrutiny from Match Review Officer Michael Christian after a collision with West Coast's Jeremy McGovern.
McGovern was taken from the ground in the hands of Eagles trainers following the clash, with Gray's decision to bump rather than tackle sure to have the Power star facing a nervous wait.
If history is anything to go by, the severity of any potential injury suffered by McGovern could also play a hand the decision on Gray's actions.
