Affectionately known as ‘Foxy’, Davies played his junior club rugby for St Clears and Whitland before coming through the Scarlets academy and going on to become one of the leading centres in world rugby.
He played six Tests on two tours with the British and Irish Lions, in 2013 in Australia and New Zealand in 2017, and was named player of the series in the 1-1 draw against the All Blacks.
Davies has played 96 Tests for Wales, captaining his nation on four occasions.
He featured in two Grand Slam-winning sides, enjoyed a further two Six Nations Championship wins and played in two World Cups.
The centre has had two stints with Scarlets, either side of a two-year spell at Clermont Auvergne in 2014-2016.
Davies was a key figure as Scarlets won the Pro12 title in the 2016-17 season.
“There was a span of five or six games in 2017 when I never enjoyed rugby as much as I did at that moment,” he said.
“The rugby we played was so much fun and natural. It felt as if we were operating at our highest level possible and the talent in that group was so high.”
Scarlets beat Munster in the 2017 Pro12 final, with Davies sharing the moment with his brother James, who retired in April 2022 because of concussion and was later given a recruitment and retention role with the region.
“Playing alongside my brother was another special moment and winning a trophy in the same side as him is something I am very proud of,” said Davies.
Scarlets’ last match in Llanelli this season is against Ulster on Saturday.
There will be a number of high-profile departures, with ex-Wales captain Ken Owens having announced his retirement last month.
Wales scrum-half Kieran Hardy is joining Ospreys next season and centre Scott Williams and prop Wyn Jones are also in line to leave.
