Shocking moment tennis star Yibing Wu collapses at Citi Open in DC, weeks after Wimbledon breathing problems

Tennis star Yibing Wu collapsed on Monday afternoon at the Mubadala Citi DC Open in the US capital.

The shocking scenes come just weeks after the Chinese player experienced a similar incident during his Wimbledon opener against Frances Tiafoe earlier this month.

Wu, 23, defeated Yosuke Watanuk 4-1 in the round of 64 at the tournament in Washington DC on Monday, but was forced to pull out of the bout.

His retirement from the match saw Watanuk, 25, automatically advance to the next round.

Footage shared by Tennis TV showed the young star collapsing as he approached his chair.

Wu, number 90 in the ATP world rankings, was beaten by Tiafoe in the opening set on a tiebreak and had just lost the first two games of the second set before complaining of breathing difficulties.
