Simon Yates is to miss the Tour de France next month due to a four-month ban given to him by the International Cycling Union.

He has been in limbo since he tested positive for the banned substance Terbutaline during Paris-Nice in March. His team, Orica-GeenEdge, has admitted responsibility for the mistake, with the substance having been included in an asthma inhaler he was using.

The suspension was given for a “non-intentional ant-doping rule violation” but because of the timing it means that Yates will not be able to take part in the Tour de France which begins nine days before the ban ends.

The team said that their doctor had failed to properly apply for a Therapeutic Use Exemption for the medication he prescribed.

In a statement Yates said, “Unfortunately as a result of an honest mistake of my team doctor, whom I trusted wholeheartedly, there will now be a doubt cast over my name, my previous results and any future glories. I would like to apologise to my colleagues for once again casting our sport in a negative light.”

He went on to say that he was very “embarrassed and ashamed” of the situation but that he is determined to move forward.

The ban has been back-dated to March 12 and he intends to return to action in the Tour of Poland next month leaving his twin brother Adam to do the Tour de France without him.

Due to the nature of his offense the ban is relatively short and he is still able to be selected for the Olympic Games. It is known that he is one of a number of riders under consideration for the Great Britain team that will be tackling the mountainous road racing courses in Rio this summer.
