London - Controversial Wales centre Gavin Henson was sacked with immediate effect by club side Cardiff Blues on Monday after causing a disturbance on the team's flight back from Scotland last weekend.
A statement issued by the Welsh regional side said: "Following a management meeting on Monday morning, Cardiff Blues can confirm that Gavin Henson has been dismissed with immediate effect."
Blues chief executive Richard Holland added: "The Cardiff Blues management have discussed the matter at length but have acted swiftly since the incident occurred on Saturday morning.
"Gavin admitted himself that his behaviour was totally unacceptable and the immediate termination of his contract sends out a clear message that behaviour like that will not be tolerated at the Blues.
"We have a duty to our supporters and sponsors to protect the good name of Cardiff Blues and those associated with our brand.
"Gavin Henson is obviously a talented rugby player and it's unfortunate that his career at the Blues has ended this way.
"However, we would like to thank him for his service and wish him the best of luck with his future career."
The 30-year-old Henson was initially suspended by his club side for the incident, which took place as the team flew back from Scotland following a 31-3 Celtic League defeat by Glasgow on Friday.
Henson issued a statement of regret on Sunday, saying: "I would like to publicly apologise for drinking on that flight, which is inappropriate behaviour".
But it was not enough to save his Cardiff career and the one-time golden boy of Welsh rugby now faces an uncertain future.
