'No problem' if Dwain Chambers runs

DOHA, Qatar -- The president of athletics' governing body says he would have "no problem" if British sprinter Dwain Chambers competes at the London Olympics.

Chambers served a two-year suspension after testing positive for a steroid in 2003. He was later banned for life from the Games by the British Olympic Association. But sport's top court recently overturned such bans, ruling they amount to a second sanction.

IAAF president Lamine Diack said Thursday that Chambers has served his suspension and should be allowed to compete if he qualifies as the rules state.

Diack is against "condemning" a drug cheat to a lifetime ban, but says the punishment should be severe to ensure the best "cleanest athletes win."
