MEXICO CITY – Mexican President Felipe Calderón fractured his shoulder after falling from his bicycle, his office said Sunday.

Calderón 46, skidded on a wet and slippery surface while doing his morning exercise Saturday, and tumbled to the ground fracturing his left shoulder and also hurting his left knee.

The former energy minister is expected to recover from the fracture in six to eight weeks, the presidential office said in a statement.

The accident did not appear to interrupt Calderón's agenda. Sunday, he received the organizers of a huge march to protest a wave of gruesome murders and kidnappings which attracted more than 150,000 Mexicans Saturday night.
