Alexander Zverev will not feature for Germany in this week's Davis Cup group stage in Hamburg after experiencing "extreme pain" and is unlikely to play again this year, he said Monday. Zverev has been sidelined since tearing ankle ligaments during his semi-final against Rafael Nadal at the French Open in June. He left the court at Roland Garros in a wheelchair and subsequently underwent surgery to repair three torn ligaments in his right ankle.
