Tennis players are forced to retire from matches with injuries all the time, but American Coco Gauff did something during Tuesday's China Open match vs. Naomi Osaka of Japan that fans aren't always used to seeing.

Coco Gauff helped carry Naomi Osaka ’s bags off the court after the former World No 1 retired from their highly anticipated China Open quarter-final with a back injury. Gauff had just levelled the match at one-set all when Osaka shook hands with her opponent, having received medical treatment earlier in the contest.

The Naomi Osaka and Coco Gauff blockbuster in Beijing has just finished in very shocking but also unfortunate circumstances as the Japanese tennis star abruptly retired from the match after the American sent their quarterfinal match into a third set.
