Rangers manager Derek McInnes has been handed a four-match touchline ban, with one game suspended, after describing a penalty award to Celtic as 'disgusting'. The incident occurred while McInnes was in charge of Hearts earlier this season. The decision to give Celtic a late penalty during a match against Motherwell prompted McInnes to make the remark, which was deemed inappropriate by football authorities. The ban means McInnes will be absent from the dugout for three league matches, with the fourth game suspended subject to future conduct. The Scottish Football Association confirmed the punishment after reviewing the case. McInnes, who took over at Rangers last month, will serve the ban starting from the next fixture. The comment was made during a post-match interview where he expressed frustration over the officiating. The club has not yet commented on the sanction.
