Merthyr RFC captain Paddy McBride swore twice on live TV as S4C were forced to apologise to viewers.
Newport RFC visited The Wern on February 15 in the Indigo Welsh Premiership. The visitors, who are second in the Indigo Welsh Premiership table, secured a 15-31 victory on the night.
Merthyr skipper McBride gave a post-match interview to former Ospreys man Ifan Phillips, who now works for S4C, and it's clear emotions were still running high.

"Discipline probably let us down in the end," he said.
We gave Newport that many chances... they're a f***ing good team to be fair. They're always looking to play rugby, and it's just the discipline to be honest with you.
"Newport, they're a good team. It's hard enough with f***ing 15 men, never mind 13. There's just different things you've got to control in the game. I thought we were in control at some points in the game. Other things slipped passed us, and that's when they started building the points then."
The language left interviewer Phillips a little flustered as he searched for the right words to continue the interview, perhaps with a producer highlighting the need for an on-air apology in his ear.
After shaking hands with McBride, Phillips hastily apologised for the coarse language and seemed to see the funny side of it.
