A leading sports psychologist has branded Nick Kyrgios’s conditional eight-week ban as too light and urged the troubled tennis star to fully commit to getting his head right.

Jeff Bond, who worked with former Wimbledon champion Pat Cash, says the ATP’s offer to reduce Kyrgios’s suspension to three weeks if the 21-year-old seeks professional help “isn’t doing anyone any favours”.

“You’re not going to solve Nick’s issues in three weeks,” Bond told AAP on Tuesday after the ATP also hit Kyrgios with an additional $32,000 fine for his Shanghai Masters meltdown last week.
