Mercedes has confirmed Lewis Hamilton has been suffering with a fever and was also involved in a road accident in Monaco on Monday and as a result delayed his flight to Brazil on the advice of doctors, but says he will race in Brazil this weekend.

A team spokesperson says the three-time F1 World Champion had to postpone his travel plans until late on Wednesday after falling ill as well as suffering a road accident on Monday.

Consequently, Hamilton missed a sponsor event in the Brazilian city which sparked concerns the Brit might miss the race altogether, but his team and the driver has confirmed he will be well enough to compete.

"No, he's not going to miss the race," a spokesperson said to Reuters. "He's going to be a day late. The doctor advised him to cancel the earlier flight so he missed a press conference today."

After the initial reports about his illness, it also came to light the British driver was involved in a small road accident in Monaco on Monday but he confirmed nobody was hurt and there was no cause for concern.

Hamilton sealed his third F1 title last month at the United States Grand Prix with three races to spare and with Mercedes also clinching the F1 Constructors' Championship, the British driver has very little left to compete for in 2015.

The 30-year-old has never won in Brazil and says he aims to break his duck in Sao Paulo this weekend in tribute to his racing idol Ayrton Senna.

Last season Hamilton's team-mate Nico Rosberg claimed the chequered flag in Brazil to set up a thrilling finale in Abu Dhabi where Hamilton was victorious to take his second F1 title.

Dear TeamLH, just wanted to let you know why things have been quiet on social media the past few days. I've not been well with a fever but I also had a road accident in Monaco on Monday night. Whilst ultimately, it is nobody's business, there are people knowing my position that will try to take advantage of the situation and make a quick buck. NO problem. Nobody was hurt, which is the most important thing. But the car was obviously damaged and I made very light contact with a stationary vehicle. Talking with the team and my doctor, we decided together that it was best for me to rest at home and leave a day later. But i am feeling better and am currently boarding the plane to Brazil. However, I am informing you because I feel we all must take responsibility for our actions. Mistakes happen to us all but what's important is that we learn from them and grow. Can't wait for the weekend Brazil Bless Lewis
