Jones is not the only late addition featuring for the Lions today.

England fly-half Marcus Smith starts at 10 against the Stormers after only being called up at the weekend.

Two Welshmen start: lock Adam Beard and wing Josh Adams.

British and Irish Lions: Hogg (capt); Adams, Daly, Henshaw, Van der Merwe; Smith, Price, Sutherland, Cowan-Dickie, Furlong, Beard, Hill, Beirne, H Watson, Conan

Replacements: George, Vunipola, Fagerson, AW Jones, Simmonds, Davies, Harris, Rees-Zammit

After this match is done, the British and Irish Lions face the Stormers in Cape Town for a final warm-up match before the Test series against South Africa.

Staggeringly, Alun Wyn Jones is on the Lions' bench just three weeks after he dislocated his shoulder playing against Japan. Preposterous.

The only people who don't seem surprised by the Wales captain's recovery are his team-mates and coaches, Wayne Pivac included.

As for Wales head coach Wayne Pivac, the purposes of these Tests against Argentina - and the win over Canada earlier this month - is to build strength in depth.

Wales are without 27 players due to injuries and British and Irish Lions call-ups, so these matches are an opportunity to expand their talent pool with an eye on the 2023 World Cup.

"The summer has been a worthwhile exercise and what we want to do as a group is sign off with a very good performance against a good tier-one nation," said Pivac.

"It's a huge challenge when you go through the player list of who is unavailable.

"When you've got five of the back three, four second rows, and three 10s missing, a whole forward pack gone and one guy who started the last Six Nations game in France, it's a tremendous opportunity.

"We're learning so much and it's been a success regardless from my point of view, but clearly we're rugby people. There is a match to be played and we want to win."

Argentina led for much of last Saturday's match despite playing with 14 men for 50 minutes following the red card to Juan Cruz Mallia.

Pumas head coach Mario Ledesma has high standards, though, and he expects an improvement from his side today.

"I was disappointed with the first match result but at the same time it was an awesome effort with 14 men for a long time," said the former Argentina hooker.

"As a result it was not that bad and we have been working to this next game. Since we started the tour we have been saying that every day is important, because of this issue of being apart for so long.

"I think we have got better and we will surely see a better game this weekend."

If you missed last week's first Test between these two sides - or just fancy jogging your memory - here are the highlights.

“Playing in heat like this can be difficult.

“I’d much prefer to be playing in heavy rain than weather like this.”

It's roasting in Cardiff this afternoon, with temperatures reaching 28 degrees Celsius.

I bet Jonathan Davies wishes he could be playing in his vest.

If you had arms like that, you'd probably wear a vest in December.

Centre Jonathan Davies captains Wales again today, and he hopes his side can end the season "on a good note" by beating Argentina.

Argentina have made two changes, both among the backs with Santiago Chocobares and Bautista Delguy starting.

Full-back Juan Cruz Mallia was sent off in last Saturday's 20-20 draw at the Principality Stadium and has been suspended for three matches for a head-high challenge on Wales scrum-half Kieran Hardy.

Santiago Carreras moves from the wing into full-back, with Delguy coming into the side. Matias Moroni is moved from centre to wing in place of Santiago Cordero, with Chocobares starting in midfield.

Argentina: Santiago Carreras; Bautista Delguy, Santiago Chocobares, Jeronimo de la Fuente, Matias Moroni; Nicolas Sanchez, Tomas Cubelli; Nahuel Tetaz Chaparro, Julian Montoya (capt), Francisco Gomez Kodela, Guido Petti, Marcos Kremer, Pablo Matera, Facundo Isa, Rodrigo Bruni.

Replacements: Facundo Bosch, Facundo Gigena, Santiago Medrano, Tomas Lavanini, Matias Alemanno, Felipe Ezcurra, Domingo Miotti, Juan Imhoff.

"With so many players away, this is a golden opportunity for Wayne Pivac to have a look at some of his younger players.

"This is a great chance for those players to make an impression."

Wales have made seven changes for this series decider.

Cardiff half-backs Tomos Williams and Jarrod Evans both start after impressing off the bench last week.

Up front, prop Gareth Thomas will make his first start and Leon Brown also comes into the front row.

Josh Turnbull replaces the injured Aaron Wainwright in the back row.

Wales: Hallam Amos; Owen Lane, Nick Tompkins, Jonathan Davies (capt), Tom Rogers; Jarrod Evans, Tomos Williams; Gareth Thomas, Elliot Dee, Leon Brown, Ben Carter, Will Rowlands, Josh Turnbull, James Botham, Ross Moriarty.

Ready for round two of Wales against Argentina? Good. You've come to the right place.

After drawing 20-20 at the Principality Stadium a week ago, the two sides meet again today for the second and final instalment of their two-Test series.

Building for the future is Wales' aim, and victory against a strong Argentina would be a fine achievement for Wayne Pivac's young side.

Without further ado, let's get to it and take a look at the teams.
