Bernard Tomic has been dropped by his agency IMG with two years left on his contract, reports SportsBusiness Journal. A series of off-court activities have left some questioning the Australian's career motivation.

The 21-year-old has been with the agency since he was 12, but has fallen out of the Top 100 following double-hip surgery after the Australian Open. Tomic was 4-8 following surgery before this week's event in Bogota, where he received a wildcard and has won his first-round match. The figures include both tour and qualifying matches.

Tomic was also reported by Australian newspapers to have attended a party in February where underage girls were offered drugs, but he was not linked to illegal activity by police. In November, he was photographed partying with high school girls at a nightclub.

Tomic’s father, John, resumed coaching him in May, having been banned from tournaments for a year by the ATP following an assault on his son’s former hitting partner that left him with a broken nose and neck injuries.

Tomic will also require a wildcard to play the U.S. Open, but there is speculation that it may go to another player following his recent performances.
