Matthew Morgan has apologised for his strongly-worded tweet while Cardiff were stranded in South Africa.

The Welsh international full-back posted his comment just after the Arms Park outfit had been thwarted in their bid to leave Cape Town for a third time.

In it, he hit out at both the United Rugby Championship and Welsh Government, rounding off his tweet with the message: "Get us the f*** out of here you clowns".

Now the 29-year-old - known throughout the game as Nipper - has put out a fresh statement, in which he explains the background to his original outburst.

Posting on Twitter, he wrote: "As reflection of my previous post, I am aware this was uncalled for and written in heat of the moment, which is out of character for me.

"It’s been a very stressful, uneasy time for all and my anxiety has been triggered by my heavily pregnant partner back home.

"I apologise for any offence caused and remain grateful for all the continued support.

"Wishing myself and the rest of team a safe journey home and exciting season ahead."

He accompanied his message with the words "Nipper is a clown".

It took Cardiff a week to eventually leave South Africa, where they had been preparing for two rounds of United Rugby Championship matches, games which were called off after the country was put on the UK Government's red travel list due to concerns over the new Omicron Covid variant.

Their departure was delayed by positive Covid tests, plus problems over securing permission for their charter plane to take off.

A travelling party of 42 players and staff finally flew out of South Africa on Friday, December 3, heading for Dublin, with a connecting flight to Heathrow to follow.

They are now undertaking 10 days of quarantine in a London hotel.

Six members of the original tour group have remained in Cape Town having tested positive for Covid.

They will begin the journey back to the UK once they have completed an isolation period.
