Sydney Thunder have terminated Afghanistan pacer Fazalhaq Farooqi's Big Bash League (BBL) contract with immediate effect after a disciplinary complaint triggered an investigation by Cricket Australia.

The complaint was regarding an incident that took place on December 15 and resulted in a hearing with Cricket Australia's Conduct Commissioner.

Four games into the 2022-23 season, the Thunder decided to break ties with Farooqi straight away after the hearing and in a statement, said "all impacted parties have been offered support".

Cricket NSW CEO Lee Germon said: "The behaviours displayed by Fazalhaq Farooqi sit outside our values and it was determined that his contract be terminated.

"Our focus now is providing the necessary support to those affected by this incident."

"Sydney Thunder have terminated the contract of Fazalhaq Farooqi, following a hearing held by Cricket Australia’s Conduct Commissioner," the Friday afternoon release read.

"Following the Commissioner's ruling, Sydney Thunder took the extra step of terminating the contract.

"The club received a complaint about the behaviour of Farooqi following an incident last Thursday and referred the matter to Cricket Australia’s Integrity Unit for investigation."

Ahead of the tournament, Sydney Thunder had said they expected Fazalhaq Farooqi to "enhance the growing reputation of cricketers from Afghanistan". The left-arm pacer was roped in after his impressive exploits in the T20 World Cup 2022 Down Under.

"We fully expect Fazalhaq will only further enhance the growing reputation of cricketers from Afghanistan for being fearless cricketers and extraordinary entertainers," a statement read.

Fazalhaq Farooqi played four matches for Sydney Thunder this season, claiming five wickets.
