Rangers goalkeeper Allan McGregor will not face any action from the Scottish FA after appearing to kick out at Celtic's Kristoffer Ajer on Sunday.
Footage shows McGregor, 36, making contact with the defender during the first half of his side's 1-0 Old Firm defeat at Celtic Park.
Ibrox manager Steven Gerrard described the act as "blatant" and said he would speak to the Scotland international.
However, McGregor will not face a notice of complaint.
Three former match officials were consulted but did not reach a unanimous agreement to take the matter forward.
All three of the ex-category one referees must arrive at the same decision for a notice to be raised.
