GAELIC channel BBC Alba delayed broadcasting a football match until after the watershed because supporters could be heard swearing from the stands.
The match between Ross County and St Mirren had been due to air at 5.30pm on Saturday but was delayed until 10.55pm amid fears the bad language would have left the channel in breach of Ofcom guidelines.
In a tweet, producers apologised and said it was down to "bad language from crowd".

A spokeswoman for BBC Alba said: "In compliance with the rules set by Ofcom, where no programme that carries offensive language can be broadcast pre-watershed, BBC Alba had no choice but to defer broadcast of (Saturday's) Ross County v St Mirren match until post-watershed due to bad language picked up from the crowds."
Ross County won the match, at the Global Energy Stadium in Dingwall, 2-1.
