Coco Gauff crashes out of Paris Olympics in tears after heated row with umpire during defeat against Donna Vekic

Vekic shocked Gauff 7-6 (9/7), 6-2 to reach the quarter-finals, but the match was overshadowed by a lengthy row between the US star and the chair umpire

Tearful Coco Gauff crashed out of the Paris Olympics at the hands of Donna Vekic on Tuesday after a heated row with the umpire as Rafael Nadal prepared to return to the baking courts.

With temperatures rocketing into the mid-30s Celsius at Roland Garros, officials activated a heat protocol, allowing a 10-minute break between the second and third sets.

In the first match on Court Philippe-Chatrier, Vekic shocked Gauff 7-6 (9/7), 6-2 to reach the quarter-finals, but the match was overshadowed by a lengthy row between the US Open champion and the chair umpire.

Gauff, the flag-bearer for the United States at the Olympic opening ceremony alongside NBA star LeBron James, made a fast start but squandered three set points before her Croatian opponent won the first-set tie-break.

The pair swapped breaks early in the second set but the match came to a standstill at the end of the sixth game as an emotional Gauff pleaded her case with the umpire.
