Nigel Mansell is F1's one-handed FIA race steward this weekend at Monaco.

The 1992 world champion walked into the Monte Carlo paddock with his arm in a sling.

What happened? "Broken collarbone," the former Ferrari, Williams and McLaren driver told Swiss newspaper Blick on Thursday.

"I fell off my bike."

Mansell, 58, is an avid road cyclist.
