European football's governing body, Uefa, has confirmed it will investigate the tackle which forced the Celtic midfielder Scott Brown out of Tuesday night's Champions League win against Benfica.
Augustin Binya was shown a straight red card by the Swedish referee Martin Hansson for the shocking challenge with five minutes of the match left at Celtic Park. Afterwards, Brown accused his opponent of trying to break his leg and called for Uefa to take action.
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 the player should face further sanctions.
A Uefa spokesman said: "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 15 November. 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."
The captain, Stephen McManus, insists Celtic have renewed hope in the Champions League after their victory. The Scottish champions went into the match bottom of Group D and knowing that another defeat would have all but ended their chances of reaching the knockout phase. Celtic play Shakhtar Donetsk at home in their next match, before facing Milan in the San Siro, and McManus said: "It was a big result and it keeps us in the mix which is what we wanted at this stage of the campaign.
"We are in with a chance, the same as the other three teams in the competition. We are a confident bunch of lads. When you play with Celtic, you have to be confident."
The goalscorer and chief tormentor of Benfica Aiden McGeady proved to be the difference between the two teams and Celtic's manager, Gordon Strachan, said he was "awesome". The club's goalkeeper, Artur Boruc, went one better and backed the 21-year-old to be better than Cristiano Ronaldo. "Aiden deserved everything he got and all the compliments," McManus said. "He was different class and it's great to see him doing it on this stage."
