After Ireland successfully defended their Six Nations championship this year, there were rumours that O'Mahony may announce his retirement from the game.

On Friday, though, Munster and the IRFU both announced that the 34-year-old has agreed to a one-year contract with the region.

"After plenty of thought, I'm delighted to have the opportunity to sign on for 1 more year with Munster and the IRFU," O'Mahony wrote on Instagram when he shared the news.

However, Munster and the IRFU both said on Friday that the 34-year-old has reached an agreement to sign a one-year contract with the area.

When he announced the news on Instagram, O'Mahony stated, "After lots of thought, I'm delighted to have the opportunity to sign on for 1 more year with Munster and the IRFU."

"I feel like it's the proper thing for me to do; it's a decision I had to make with my coaches and, more importantly, my family.

"I feel there's more left in me to give."

"I've always tried to do my best for my province and country, and I'll keep doing that for the rest of this season and the next," he continued.

"Who knows what lies ahead, but I’ve had nothing but great years and I will endeavour to make this last chapter of my playing career the best of all."
