The Celtic captain was once again instrumental in the heart of the midfield during the club’s 4-1 defeat of Hamilton. However, he faces a sweat to face Rangers if he is reported for an apparent kick at wing-back Giannis Skondras.
Footage showed the 32-year-old appear to flick his boot at the Greek defender following a foul committed by Brown during the first-half of Friday’s encounter shown on BT Sport.
A visibly unhappy Skondras confronted Brown as the players waited for a set-piece to be taken moments latter.
After the game Brown said: “I don’t know what happened. He (Skondras) was moaning about me bumping him in the face but there was nothing in it.”
The incident was missed by referee Don Robertson but he could still face the prospect of a ban if it is reported to SFA compliance officer Tony McGlennan.
It was picked up by both Chris Sutton and Ally McCoist, the latter saying the player was daft.
Brown was involved in a similar incident in the first league game of the season when he appeared to catch Hearts midfielder Arnaud Djoum.
