Wales vs Scotland live: Joe Hawkins sent to sin bin as struggling hosts eye Six Nations success in Cardiff

Duhan Van der Merwe gets his first touch but is tightly marked by Louis Rees-Zammit and Josh Adams.

Wales concede a penalty, allowing Scotland to clear, but Huw Jones is stopped just short in the corner.

Earlier, Joe Hawkins might be in trouble for a previous challenge.

After just 2 minutes into his international debut, Gabriel Hamer-Webb is forced off with a nosebleed.

Blair Murray comes on as the blood replacement.

Matthew Carley blows the whistle to start his 50th test.

Matt Ferguson claims the ball and Ben White clears it out of the box.

Sam Costelow gets the game underway at the Principality Stadium.

The Principality Stadium is lit with red lasers under the roof.

As they belt out their anthems.

On his history with Scotland: “It’s a bit different being in the other box, but this is an amazing fixture, brings the best out of the crowd. It’s the best of the Six Nations, so I’m very excited.”

On Finn Russell: “He’s an unbelievable player, we know he’s going to have moments, but we’re still developing what we want to be, around a defensive system. If we get it right we can cause problems on transition. Finn is Finn, there’s going to be the unexpected as well so it’s being prepared for that.”

On his change in the back row: “Taine has made real impact off bench. The game last week was really fast paced, we know Scotland don’t kick the ball as much as other nations, so we want to match that up a bit but also play how we want with some extra mobility.”

“We’ve got to create our own energy today, we know this is one of the toughest environments to play in, the noise the crowd make and it’s a team that’s desperate to win.

“We have to show equal desire [to last week], and build on a good performance. It’s a new challenge and a challenge for our players to back that performance up.

“I’m worried about what they can bring, they’ve an excellent team, individually are very good. They’re building a game, and have excellent coaches. We expect a top quality game today.”

On Blair Kinghorn and Duhan van der Merwe

“Yeah they’ve been chomping at the bit all week, Blair went very well vs Toulouse last week and Duhan has trained excellently.

“They have to work hard; both wingers and Tom Jordan have set really good levels with their commitment for high balls and work off it [so far].”

This is a meeting of the two worst lineouts in the competition so far. The sample size is small, and Scotland had exceptional circumstances in a rainy Rome, but the onus will be on both hookers to hit their jumpers today. There are plenty to target, too - Gregor Brown is a long-limbed option on the blindside for Scotland while Taine Plumtree has all sorts of spring in the No 6 shirt for Wales.

Joe Hawkins says Wales must beware Scotland's midfield threat of Sione Tuipulotu and Huw Jones in today’s Six Nations clash.

Hawkins and fellow Scarlets centre Eddie James line up against the British and Irish Lions pair as Wales attempt to end a sorry run of 13 successive Six Nations defeats.

Captain Tuipulotu and Jones, who scored two tries in the 31-20 Calcutta Cup victory over England last weekend, form arguably the best centre partnership in the Championship and have fellow Lion Finn Russell inside them at fly-half pulling Scottish strings.

Hawkins said: "Tuipulotu's obviously a powerful ball carrier, but he's got nice subtle skills as well. Jones has got a bit of gas and some nice running lines, so they complement each other well.

"They're quite a settled centre partnership, so whoever gets the chance (to play for Wales) this is a good test. Russell has a good passing game and good kicking game, what he's done at Bath and with Scotland speaks for itself. He seems to just play what he sees really, which is to play off instinct, and that is good for any player."

Gabe Hamer-Webb has an interesting story, having shown real promise as a teenage footballer before a somewhat nomadic journey through rugby as a young player. There have been stints with Southland in New Zealand, Northampton and Hartpury University having come through at Bath, but Hamer-Webb really found form towards the end of his time with Cardiff last year.

This first cap comes after an impressive start with Leicester, earning him a longer-term deal despite limited opportunities during the first few months of the season. Duhan van der Merwe will challenge him today, I’m sure, but Hamer-Webb will hope to stake a claim.
