Commentator Peter Alliss caused a sexism row by referring to the short skirt worn by golf hero Sergio Garcia's fiancee.
The 86-year-old made the off mic remark about Angela Akins in BBC coverage of The Masters, The Sun reports.
As images were shown of Angela, 31, reacting to Garcia's win, Alliss's muffled voice was heard saying: "She's got the shortest skirt on the campus."
Last night the BBC confirmed Alliss believed he was off air when he made the "lighthearted" comment and accepts it was "inappropriate".
The remark was picked up by viewers who watched the dramatic events on Monday morning, when the Spaniard beat Brit rival Justin Rose to claim his first ever major in 74 attempts.
