Denmark replaces doping-tainted mountain biker Riis Andersen with Nielsen for Beijing Olympics

Mountain bike rider Klaus Nielsen was selected in Denmark's Olympic squad Tuesday as a replacement for Peter Riis Andersen, who was barred from the Beijing Games after admitting he had doped.

The 28-year-old Nielsen was picked by Denmark's Olympic committee and is the 84th athlete on the team.

Riis Andersen admitted Monday he had taken the banned blood-booster EPO and said he would quit professional cycling.

Nielsen finished second to Riis Andersen in the Danish mountain bike championships on July 20.
