Armstrong has to cancel

SAN FRANCISCO — Cyclist Lance Armstrong withdrew from Sunday’s street race here because of tendinitis in his right knee.

Armstrong, who won his record sixth consecutive Tour de France title in July, had already arrived in San Francisco when his knee began bothering him.

The race features a top international field, including nine who competed in the Athens Olympics.

“This problem popped up for the first time ever toward the end of the Tour de France and I thought it would go away with the proper rest,” Armstrong said Friday. “It continued to hurt during training and flared up this week.”
