Paris - Briton Adam Yates was handed a 10-second penalty by the Tour de France's race jury for a "handsling" in Friday's 19th stage.
The Orica-Bike Exchange rider, who benefited from a push via the hand of team-mate Ruben Plaza, was also given a fine of 200 Swiss francs ($202).
Yates, 23, now trails overall leader Chris Froome by four minutes 46 seconds and, more importantly, second-placed Romain Bardet of France by 35 seconds.
Saturday's 20th stage, the last competitive ride on the Tour, is a demanding 146.5km trek in the Alps.
