Sounds like there has been some argy bargy going on over in the Davis Cup matches.
Belgian V Chile- Zizou Bergs and Cristian Garin collided, which lead to Garin being disqualified after he wouldn't finish the match (said he was injured and wouldn't continure without medical assistance, which he got, and was said to be fit to carry on) He was given 3 consecutive time violations, because he refused to continue playing and that was the end.
In the France v Brazil match, Arthue Fils (who won) was having a big row with the umpire over a challenge that may or may not have happened and things got ugly. Fils is getting a bit of a reputation for letting his emotions get the better of him.
Rotterdam/Dallas start today -obviously easier to watch one than the other
