Dwain Chambers' athletics career could be over after the announcement that he has signed a contract with German gridiron side Hamburg Sea Devils.
The former European 100m champion, who was banned for two years for doping offences, successfully completed a training camp in Tampa last Thursday.
Hamburg coach Jack Bicknell said: "Chambers has not only excellent speed, but also safe hands."
Chambers said: "I'm very happy to be allowed to play for the Sea Devils."
The 28-year-old first impressed coaches during a trial in Cologne last November.
He was then invited to a training weekend in Barcelona, where he convinced coaches he was good enough to be part of a March camp in Florida.
Chambers is determined to pursue a career in American Football.
In December his agent, Cubie Seegobin, told BBC Sport that the former European 100m champion would not participate in the indoor athletics season and was unlikely to compete in the sport again.
Chambers returned to athletics last June after being banned following a positive test for the steroid THG.
Under the terms of his return, he must use future track earnings to pay back any prize money he won while competing on steroids.
Seegobin said: "Personally, I think because we have so much money to pay back, if he can find another way to make a living he will."
