Six countries, 15 games -- the stage is set for England, Ireland, Wales, France, Scotland and Italy to do battle in the annual Six Nations Championship.
This year's tournament kicks off in Cardiff, where Wales hosts Scotland.
Wales has three home games at the 74,500-seat Principality Stadium, also welcoming Italy and France in the final two weekends of action.
Coach Warren Gatland returns to the Six Nations after leading the British and Irish Lions on their New Zealand tour last year. After a fifth-place finish in 2017, Welsh fans will be hopeful of improvement this year. Gatland has coached the side to two Six Nations grand slams (five wins from five) during his decade in charge -- in 2008 and 2012.
With a number of high-profile injuries, victory this year could be a tall order for Wales. Lions captain Sam Warburton will be missed -- he underwent knee surgery last year.
For Scotland, however, the signs are more promising. A record victory over Australia and a narrow defeat by the All Blacks in November last year will bring confidence to fans and players alike.
Stuart Hogg has emerged as a star player over the past few years. He was named player of the tournament in 2016 and 2017 and has 10 Six Nations tries to his name, more than any other Scottish player.
Coach Gregor Townsend (left) took charge of the side in May last year, in which time he has overseen four wins and two losses. He's pictured here with captain John Barclay as the pair celebrate beating Australia.
Passionate crowds can be expected to fill Murrayfield stadium in Edinburgh when France and England visit, the latter to compete for the Calcutta Cup.
Ireland spoiled England's chances of back-to-back grand slams with a 13-9 victory in Dublin last year. Joe Schmidt's men last won the Six Nations in 2015.
New Zealander Schmidt started his coaching tenure with Ireland with two Six Nations titles.
The familiar face of Johnny Sexton will marshal Ireland's back line. He has formed a trusty half-back partnership with scrumhalf Conor Murray.
The distinctive, curved roof of the Aviva Stadium in Dublin will play host to Irish encounters with Italy, Wales and Scotland.
There will be a first in French rugby as the Orange Vélodrome in Marseille becomes the first venue outside Paris to host a Six Nations game. Italy travels there on February 23.
New year, new coach, but will this be a new beginning for France? Les Bleus have fallen upon testing times of late and will hope to be rejuvenated by a young squad and new coach Jacques Brunel (right).
Seven wins in 21 games under previous coach Guy Noves gave French fans little reason to cheer.
Les Bleus do, however, have "X-factor" players. Fijian-born Virimi Vakatawa has been an explosive presence on the wing, bagging six tries in 15 games.
England is favorite ahead of this year's Six Nations after winning back-to-back championships in 2016 and 2017.
The likes of fly-half Owen Farrell and center Jonathan Joseph have thrived under Jones. Joseph has 10 Six Nations tries to his name and Farrell has amassed 304 points -- only Jonny Wilkinson has more for England.
Twickenham stadium in London is the world's largest dedicated rugby venue with a capacity of 82,000. This year it hosts England's mouth-watering clashes with Ireland and Wales.
Italy tends to struggle in the Six Nations, having not finished higher than fourth since its inclusion in 2000. The Azzurri will hope to avoid a dreaded "wooden spoon" (sixth-place finish) for the 13th time.
The 73,000-seat Stadio Olimpico in Rome is also home to football teams Lazio and AS Roma.
No. 8 and captain Sergio Parisse has been a warrior for Italian rugby for so many years. Despite numerous gargantuan performances for the Azzurri, he could become the first player ever to lose 100 Test matches.
