Petr Cech confessed that as soon as he starts to doubt whether he should put his body on the line, he will leave the game.
The 29-year-old required emergency surgery in 2006 following an incident with former Reading midfielder, Stephen Hunt, where the Czech keeper was kicked in the head, fracturing his skull.
Since the accident, Cech has played wearing protective head gear, but has not lost any of his bravery, an aspect of his game clearly marked with his collision with Fulham’s Orlando Sa in last week’s League Cup tie.
"I had a concussion last week,” he told The Daily Mirror. “When I came inside to the dressing room I couldn't see properly and I didn't have the awareness of the space.
The Chelsea keeper was rushed to hospital after suffering concussion, which left him with blurred vision, preventing him from continuing in the game.
He added, "My head was shaken. I could feel it but when I stood up I was fine. At that point I was absolutely fine. But at half-time as soon as I sat down I couldn't stand up. I went to hospital and had a scan. With my history they were not taking any chances."
"The procedure is the same with any player who has concussion, just to make sure nothing is happening inside. But all was clear and I was able to train on Friday."
The Czech international was fit for Saturday’s Premier League tie with Swansea and is excited to return to the side ahead of their Champions League clash with Valencia on Wednesday, but admits that as soon as fear creeps into his game, he may have to retire.
He continued, "I had a headache on Saturday morning and we weren't sure if I would be able to play. I went out for the warm-up and we said 'if I'm OK in the warm-up then I play. But if I'm not right I'm not going to play.' So I did the warm-up and I was OK to play and I was fine.
"At the time it was more the emotion because my head went back like when you get a right hook in boxing. What happened I don't know. I think the helmet took most of the impact. As I said, I thought I would be OK I just didn't know if I would be ready to play.
"One day if I feel the fear of putting my head in the middle of some battle or scrum, then I stop. But so far I haven't felt that."
Certainly Not A Good News For Any Chelsea Fan
