Denis Shapovalov had to retire from his opening match at the Paris Masters on Monday because of a lower-body injury. He was up 4-1 in the third set against Karen Khachanov when he stopped, a tough way for his week in Paris to end.
The Canadian was in front when he called it quits, which makes this exit sting even more.
The injury was described as lower-body, with no further details given about how serious it is.
Khachanov moves on to the next round, while fans wait for news on Shapovalov's condition.
