Kyrgios beginning his probation after accepting penalty
Nick Kyrgios' six-month probationary period will start today after the Australian opted not to appeal the punishment handed down by the ATP last week.
Kyrgios faces a 16-week ban from ATP tournaments and a fine of $25,000 (£20,000) if he violates certain conditions during the next six months.
Those include not receiving code violations for verbal or physical abuse of officials or spectators, visible obscenities or an offence of unsportsmanlike conduct, such as spitting, towards officials or spectators.
Kyrgios must also see a specialist in behavioural management during the off-season and seek support from a mental coach during ATP tournaments.
The punishment was a result of a match at the Western & Southern Open in Cincinnati in August when Kyrgios committed eight separate offences, including verbally abusing umpire Fergus Murphy and spitting in the direction of the official.
He was fined an initial $113,000 (£90,000) but the ATP launched an investigation, which concluded there was a pattern of behaviour related to Kyrgios' verbal abuse of officials and fans.
