French Open: Alexander Zverev expresses concerns that ankle injury is 'very serious'
Alexander Zverev backed Rafael Nadal to go on and win a 14th French Open title after revealing concerns that the ankle injury which forced him to withdraw from Friday's semi-final against the Spaniard is "very serious". Zverev had to be pushed off the Philippe Chatrier court on a wheelchair after twisting his ankle late in the second set as he trailed 7-6(8), 6-6 in his meeting with the 21-time Grand Slam champion. "Very difficult moment for me today on the court, obviously a fantastic match until what happened," Zverev said in a video posted on the French Open's Twitter account.
