man Dean and Cavendish's leadout man Mark Renshaw clashed for position at the head of the peloton in the stage's final meters. As Dean led Farrar up the middle of the road with Renshaw to his left, the Aussie responded by head-butting him. Renshaw later stated that he was trying to keep Dean from maneuvering him into the roadside barricades, with safety as much a concern as victory, and Dean's line did deviate slightly as he rode. Amid the chaos, the three principal sprinters jumped for an unusually long final kick to the line, starting out. Race officials later expelled Renshaw from the Tour for the headbutting. Dean was not punished for the incident, though the possibility for penalty existed – Cavendish himself was assessed a penalty in the 2009 Tour de France for similar irregular sprinting. The next day, Farrar left the race, revealing that he had sustained a broken wrist when he crashed in Belgium and rode the next nine days in severe pain. Hunter had also abandoned, the day before. Hesjedal found his form again in stage 15, a difficult mountain stage which crossed the Port de Balès. He was 16th on the stage, four minutes back of the solo winner and one minute back of new race leader Contador, but he gained time against riders like Joaquim Rodríguez, Chris Horner, and Ivan Basso, who had been ahead of him. This result put him back in the top ten overall. He further showed well in the race's queen stage, ending at the Col du Tourmalet. He finished fourth on the day, again ceding time to Contador but gaining time against almost everyone else, moving from tenth to eighth. The team had just one sprinter left of three for the flat stage 18. Cavendish won the stage handily, having a five bike length advantage over Dean in second. In the stage 19 time trial, Zabriskie was fifth. Partially due to a drastic change in wind direction as the day went on, stage winner Cancellara and the second placed Tony Martin had much better times than anyone else. Zabriskie's fifth place was three minutes off Cancellara's time, a gap of unusual size for a time trial among top level professionals. Hesjedal was 52nd on the day, but since Rodríguez was 154th and over ten minutes off Cancellara's time, Hesjedal moved up to seventh. In the Tour's largely ceremonial final
