I don't think this got discussed, but there was a big kerfuffle at DC this weekend in the Chile v. Belgium tie of Garin v. Bergs. Wondering what people think. Bergs hit Garin in the cheek/eyesocket? with his shoulder while celebrating his late break of serve as he approached the sideline for the change of ends. He got a warning for unsportsmanlike conduct, but was not defaulted for hurting Garin. Everyone agrees it was unintentional, but these things usually are. Only that, usually the ball is struck or the racquet is thrown in anger and frustration, and usually the players are on the court. And Davis Cup does seem to encourage a raucous atmosphere, and going to the team at changeovers. Garin, after being treated and cleared to play, refused to play on and was eventually defaulted for time violations, giving Belgium the win over Chile. The article below includes a video of the incident.
Bergs collided with Garin after celebrating a break of serve at 5-5 in the third set, and after the latter refused to resume play, he received a game penalty for consecutive time violations to lose the match.
