Alexander Zverev has undergone surgery on torn ankle ligaments following his fall in the French Open semi-final against Rafael Nadal. Zverev fell and twisted his ankle at the end of the second set at Roland Garros on Friday, yelling in pain as Nadal rushed around the net to help. The German was helped to his feet but taken off the court in a wheelchair for treatment. After five minutes the 25-year-old re-emerged on crutches to inform the umpire that he could not continue. Now, all three outer ligaments of the right ankle had to be operated in order to achieve full stability of the ankle in the shortest possibly time. A come back date was not given.
