Kingsley Coman was forced off with a serious-looking knee injury after scoring the opening goal in Bayern Munich’s victory over Tottenham.
The 23-year-old forward, who has endured a succession of injuries, slipped on the pitch and landed awkwardly on his left leg in the 27th minute.
BT Sport co-commentator Jermaine Jenas said he feared the winger may have torn his anterior cruciate ligament.
Coman had put the Bundesliga side ahead in the 14th minute at Allianz Arena with a calm finish into the bottom corner.
But as he chased down a pass, Coman’s left foot appeared to get stuck in the turf.
The France international had to be helped to the dressing room after receiving treatment on the pitch.
On seeing the replay, Jenas said: ‘Oh my god, it’s a bad one’.
He added: ‘I have seen what happened and it is not good. When I did my ACL I got up and walked off and went to the game that day and walked up and downstairs and was fine. You don’t realise until the testing what you have done.
‘If he hasn’t done anything serious, I will be in absolute shock.’
Afterward, caretaker boss, Hansi Flick said: ‘His injury obviously overshadows the win. We don’t know how serious it is yet, he is still undergoing examinations.’
Bayern Munich completed a perfect six victories in Champions League Group B with a 3-1 home win over Tottenham Hotspur on Wednesday with Coman, Thomas Mueller and Philippe Coutinho all on target.

Bayern had already qualified for the last 16 as group winners and with Tottenham also through as runners-up with 10 points there was little at stake but the hosts turned on the style.
They became only the seventh team to win all six group games in the Champions League.
