Sunderland sack former youth captain Lewis Gibbons after cocaine test Gibbon had intended to appeal against the club's decision, but has since accepted there is no way back for him with Sunderland after the failed drug test and their zero tolerance policy. The 17 year-old has also been banned for two years by the Football Association for breaching their anti-doping rules after he failed a drug test following a Under-18s match against Aston Villa in September last year. Sunderland academy manager Ged McNamee said: "Lewis not only let our club down, he let himself down and his team-mates down massively. We took the strongest possible action in terminating his contract as every footballer knows the severe consequences of this type of offence.
