The recent reports that Jon 'Bones' Jones has been axed from UFC 200 over a failed Anti-Doping test has sent shockwaves through the world of sports. But doping isn't reserved only for the UFC, WWE or even MLB.
Several of the biggest soccer stars in the world have been unable to keep clean their whole lives - whether it's due to doping or recreational drugs.
Here we take a look at five of the most high-profile players to ever get banned or convicted for failing drug tests:
5. Jaap Stam
A defensive stalwart for Manchester United, PSV Eindhoven and the Netherlands' national team, Stam failed a drug test for nandrolone shortly after leaving Man United for Lazio and received a five-month ban that was later reduced to four months.
Stam went on to finish his highly-successful career with Lazio, Milan and Ajax, whil making significant caps for the Netherlands before calling it a career.
4. Pep Guardiola
Yes, the man who has won countless titles with Barcelona and Bayern Munich once found himself in serious hot-water over a failed-drug test as a player in 2001. He fought the case for over half a decade before finally being cleared.
During the process, Guardiola received a seven-month suspended prison sentence - which was overturned once he was finally cleared.
3. Mamadou Sakho
A star defender for Liverpool, the France and Reds defender received a UEFA ban for doping at the tail-end of the 2015-16 season. The ban prevented Sakho from representing the Reds in the Europa League Final loss to Sevilla and resulted in his removal from the French national team for Euro 2016 in a controversial decision by Didier Deschamps.

2. Adrian Mutu
Once a prized signing for Chelsea, Mutu was flagged on several occasions for cocaine and doping. Mutu made a grand total of 27 league appearances for the Blues before being axed by the club over a failed drugs test for cocaine - which led to a seven-month ban - as well as a messy breach of contract saga.
He joined Juventus briefly before a much more successful move to Fiorentina. But after three years and 46 league goals, he was banned six months for doping and once again charged with breach of contract.
1. Diego Maradona
Arguably the greatest soccer player in history, Maradona was sadly addicted to cocaine for a good portion of his life - and his use of it nearly cost him his life before he finally kicked the habit.
In 1991, Maradona received a 15-month football ban for his cocaine use, and finally returned to football with Sevilla in 1992 as a shell of the once-dominant superstar.
