UEFA have confirmed they will investigate the tackle which forced Celtic midfielder Scott Brown out of last night's Champions League game against Benfica.
Augustin Binya was shown a straight red card by Swedish referee Martin Hansson for the shocking challenge with five minutes of the match remaining at Celtic Park.
Afterwards, Brown accused his opponent of trying to break his leg and urged UEFA to take further action against the Benfica player.
Binya faces at least a one-match ban and, because he was sent off, the governing body will automatically investigate the incident and decide later this month whether he should face further sanctions.
A UEFA spokesman confirmed: 'We haven't received the reports of the referee or the match delegate yet but we always open a disciplinary case for a red card.
'This will be on the agenda of the next control and disciplinary body meeting on November 15.
'There will be at least a one-match ban but all red cards are judged individually so we will need to wait until the meeting to see if there will be a further ban.'
Scotland assistant manager Roy Aitken was appalled by the tackle on Brown.
The challenge could have ruled the midfielder out of Scotland's crucial Euro 2008 qualifier against Italy next week, however Brown was lucky and sustained no serious damage.
Aitken believes it could have ruined the former Hibernian player's career, and insists UEFA must hit Binya with a long-term suspension to show they take such fouls seriously.
'It was a career-threatening tackle,' said the former Celtic captain. 'There's no way he [Binya] went for the ball at all. He went completely over the top of the ball. Scott went for the ball himself.
'He's so lucky and hopefully he's escaped without any major injury.'
Aitken is looking for UEFA to impose more than the mandatory one-match suspension.
He told Sky Sports News: 'It's not for me to say what would be a fitting punishment, but if we're going to stamp out that sort of challenge within the game, and if FIFA and UEFA are talking about cleaning the game up completely, that sort of challenge is just totally out of order.
'They should look at that one and decide themselves - it definitely should be more severe than just a two or three-game ban.
'I think a lesson should be learnt from that this and a precedent should be set. Any kind of challenge like that, which is career-threatening to the opposite player, should really be hit severely.'
