The AFL's Match Review has not charged Port Adelaide ruckman Ivan Soldo for a collision that was expected to have gained the attention of the MRO.
A first-quarter incident involving Soldo saw the Power tall collide with Carlton defender Mitch McGovern as both players contended for a ground ball, with the latter coming off second best as Soldo's right arm made contact with McGovern's head.
McGovern was able to return to his feet and play out the game following the incident.
It is likely the incident was at least assessed by the MRO, who has not charged Soldo with forceful front-on contact.
The MRO would've needed to believe Soldo was not reasonably contesting for the ball to have charged him with forceful front-on contact, while any circumstances outside the control of Soldo that led to the incident would've also worked in the Port Adelaide big man's favour.
With no charge handed down, Soldo will be free to play in the Power's next game against GWS on Sunday, June 16 - which will follow the club's Round 13 bye.
No other players were charged from Thursday's game between Port Adelaide and Carlton.
