Former Dutch professional cyclist Teo Muis has been given a lifetime ban for injecting his 17-year-old son with performance enhancing drugs.

Jesse Muis, now 18, was given a four-year ban in 2015, a punishment he said came as a result of missing a drugs test after a junior race in Flanders.

But it has now emerged Muis Jnr did take the test, which found traces of amphetamine and nandrolone, an anabolic steroid.

The four-year ban has since been halved after it emerged that Muis Snr, who spent two years with the Spanish Orbea team in the 1980s, administered the banned substances without his son's knowledge.

According to evidence heard at a Dutch Cycling Federation (KNWU) appeal hearing, Muis Jnr thought he was being injected with multivitamins.

A KNWU statement read: “The defendant is suspended by a ruling of the Institute for Sports Law with immediate effect for life and, therefore, must in no way [be] concerned or take part in competitions or training.”

It continued: “The person concerned, in November/December 2014, at some point prior to a doping control which took place in 2015, in his capacity as facilitator/coach, administered nandrolone to his then minor son, who is also a member of the National Federation.”
