Shapovalov, 17, was disqualified after striking chair umpire Arnaud Gabas in the eye with the ball in Ottawa on Sunday, gifting singles opponent Kyle Edmund a victory that gave Britain a 3-2 win.

The ITF fined Shapovalov $7,000 (6,520 euros), rather than the maximum $10,000, after accepting he had not intentionally struck Gabas after smacking a ball off the court in frustration at losing a point.

In a statement published on his Twitter account before the fine was announced, Shapovalov wrote: "There is no excuse for this behaviour and I take full responsibility for my action.

"I'm very sorry to Mr Gabas, to whom I apologised in person. Very sorry for letting my Davis Cup team-mates down and for letting my country down.

"I apologise to all the tennis fans, to my supporters and my sponsors. I feel ashamed of my unprofessional behaviour and will accept any consequences as a result of my action."

Israel-born Shapovalov was trailing Edmund 6-3, 6-4, 2-1 in the decisive World Group first-round tie when the incident happened.

Gabas was taken to hospital in Ottawa as a precaution after being left with bruising and swelling around his left eye, but no serious damage was found.
Britain will play France in the quarter-finals in April.
