George Hook regrets his decision to issue a threat of legal action against both Johnny Sexton and the Irish Times.
In last Saturday's Irish Times, it was disclosed that the former RTÉ rugby analyst was threatening to sue the Irish out-half and the newspaper over comments which Sexton made in an interview with Gerry Thornley a week previous.
Speaking on The Late Late Show, Hook related his repentance.
Do I regret what I did? I absolutely regret what I did.
There's a situation when you're angry, you're hurt, you're offended; you should really count up to ten - I didn't get past one.
Hook also thanked Sexton for the 'enormous favour' which he had done for the 74-year-old.
Sexton comments - and Hook's subsequent threat of legal action - gave the broadcaster the chance to appear on RTÉ and address the nation about concussion in rugby.
If I tell lies about brain damage in rugby union, which may lead to dementia, Alzheimer's, suicide, drug abuse, domestic violence - then I am a charlatan. If I'm a charlatan I should be drummed off the national airwaves and the national newspapers.
If I stay silent, who speaks for Sarah Chesters and Lily Patridge? The who women who died in the last 12 months after playing rugby. Who speaks for Ben Robinson, who died on the rugby field in Carrickfergus in front of his mother? Who speaks for Luke Neville who was awarded €2.7m in damages because of the irreparable damage to his health and career prospects?
This is the most important thing I have ever done in my life and I am not going to be silenced about it.
