World number two men's singles tennis player Alexander Zverev offered support to 24-time Grand Slam champion Novak Djokovic after the latter retired hurt from Australian Open 2025 semi-final. "Please don't boo a player when he goes out injured," Zverev said. He added, "If Djokovic cannot continue a tennis match, it really means he cannot." Zverev reached final following Djokovic's withdrawal.
