By successfully defending himself against a positive test for nandrolone, Greg Rusedski has the chance to resurrect his once-promising career.
Rusedski's career has been dogged by a fragile body and temperament
At the start of 2004, the British number two was keen to put a year of injuries behind him and focus his efforts on one last tilt at glory.
Instead, the 30-year-old had to face the biggest challenge of his career - clearing his name and attempting to make sure he would not be remembered primarily as a drugs cheat.
By doing that, he has the opportunity for another new start after several months on the sidelines.
A sometimes prickly character who has rarely let his guard down, it remains to be seen how such a public ordeal will affect Rusedski.
Although climbing to the heights he reached earlier in his career is probably out of the question, his sense of injustice at his treatment may now spur him to one last hurrah.
He reached his peak in 1997 when he made the final of the US Open, the first Briton to reach a Grand Slam final since Fred Perry in 1936.
Despite losing to Australia's Pat Rafter, Rusedski's efforts saw him accelerate up the rankings to a career-best of number four.
NANDROLONE IN TENNIS
Escapes ban under "exceptional circumstances"
One year ban
Six month ban
Positive test revealed on 8 Jan 2004. Cleared on 10 March 2004.
At the age of 24 it seemed it was only a matter of time before he landed one of the game's four major titles, but the left-hander has never been able to take that extra step.
He enjoyed success in less prestigious events, his biggest tournament win coming in the 1999 Grand Slam Cup, as well as gaining notoriety for the game's fastest serve, though his record of 149mph has since been beaten by Andy Roddick.
And he also had the satisfaction of beating two world number ones to land tournament victories.
In 1998 it was Pete Sampras in the Paris Indoor final and in 2001 he beat Andre Agassi in straight sets in San Jose.
But as well as wins, Rusedski racked up injuries and coaches in seemingly equal measure.
Injury first intervened in 1998 when he hurt his ankle in the build-up to Wimbledon.
More recently, he required surgery on his left foot and knee, as well as suffering from a series of back problems.
RUSEDSKI'S UPS AND DOWNS
Born: 6.9.73 in Montreal
1991: Turns pro
1995: Gains British citizenship
1997: US Open runner-up, new British number one and wins BBC Sports Personality
1999: Wins Grand Slam Cup
2002: Injured at US Open
2003: Plagued by injury
2004: Tests positive for nandrolone
He also worked his way through a number of high-profile coaches, including a particularly fractious relationship with Pat Cash, and won a reputation as a temperamental character.
But the true measure of any British tennis player comes at Wimbledon, where Rusedski was repeatedly overshadowed by compatriot Tim Henman.
In addition Rusedski never endeared himself to the SW19 set, who always preferred the mild-mannered Henman.
While "Henmania" grips the tournament on a yearly basis, Rusedski was often cast in a supporting role.
Phenomenal matches, including his 2002 victory over Andy Roddick, were routinely followed by early exits.
His Wimbledon legacy may end up being the furious tirade at umpire Lars Graff in the match against Roddick in 2003, rather than that straight sets win from 12 months earlier.
Rusedski, who took British citizenship in 1995, never quite won over the critics.
But being cleared of doping gives him one more chance to silence those doubters.
