Melbourne key forward Aidan Johnson has received a two-match ban for his high bump on St Kilda's Nasiah Wanganeen-Milera.

Mature age draftee Johnson earned his second suspension of the season after bumping Wanganeen-Milera mid-jump in the Demons' 28-point loss to the Saints in Alice Springs.

Wanganeen-Milera missed most of the second term but passed a concussion assessment and finished with 29 disposals.

The incident was graded as careless conduct, high impact and high contact.

Johnson is set to miss the King's Birthday blockbuster against Collingwood and their round-14 clash against Port Adelaide.

While Wanganeen-Milera was able to see out the game, Melbourne coach Simon Goodwin had admitted the contact with his head spelled trouble for Johnson.

The 25-year-old, who was pick No.68 in last year's national draft, has played only five games, after serving a one-match ban for a dangerous tackle in round one.

"Obviously when someone comes off to get assessed they're going to have a look at it, so we'll just let that play out as the week unfolds and see where that sits," Goodwin said after the match.

"Fortunately for Nasaiah, he came back on the ground and passed his concussion test."

Melbourne livewire Kysaiah Pickett was charged with striking Marcus Windhager and can accept a $3125 fine for his third such offence with an early plea.

The Demons pair were the only players from Sunday's matches to draw action from the match review officer.
