How do I follow it?
It's live on Sky. But you can hear a free audio call from the voice of New Zealand Rugby Nigel Yalden on Radio Sport. And there's also the popular live blog on nzherald.co.nz.
What are the two teams?
British and Irish Lions coach Warren Gatland named the following team to face the Chiefs:
15 Leigh Williams, 14 Jack Nowell, 13 Jared Payne, 12 Robbie Henshaw, 11 Elliot Daly, 10 Dan Biggar, 9 Greig Laidlaw, 1 Joe Marler, 2 Rory Best (c), 3 Dan Cole, 4 Ian Henderson, 5 Courtney Lawes, 6 James Haskell, 7 Joe Tipuric, 8 CJ Stander. Reserves: Kristian Dacey, Allan Dell, Tomas Francis, Cory Hill, Alun-Wyn Jones, Gareth Davies, Finn Russell, Tom Seymour.
Rory Best will captain the side, capping a memorable few days for the hooker who also received an OBE on the weekend.
Kiwi Jared Payne and Robbie Henshaw are re-united in midfield while the back three is Liam Williams with England wingers Elliot Daly and Jack Nowell either side of him.
Dave Rennie's Chiefs side is:
15 Shaun Stevenson, 14 Toni Pulu, 13 Tim Nanai-Williams, 12 Johnny Fa'auli, 11 Solomon Alaimalo, 10 Stephen Donald (c), 9 Finlay Christie, 1 Tom Sanders, 2 Lachlan Boshier, 3 Mitch Brown, 4 Michael Allardice, 5 Dominic Bird, 6 Nepo Laulala, 7 Liam Polwart, Siegfried Fisiihoi. Reserves: Hika Elliott, Aidan Ross, Atu Moli, Luteru Laulala, Chase Tiatia.
The Chiefs are obviously missing their All Blacks but have still named a formidable line-up.
World Cup winner and folk hero Stephen Donald will captain the side.
Tim Nanai-Williams and Johnny Fa'auli form a creative midfield and Shaun Stevenson will take some stopping at fullback.
What are the Lions saying?
Sam Warburton continues to chase full match sharpness, and could well take a seat on the bench for Saturday's first All Blacks Test in Auckland.
"There's no doubt that there's some pressure on certain players and certain combinations have gone well," said Gatland, when quizzed on Warburton's situation.
"A lot of those guys who played against the Crusaders did exceptionally well, and last night's performance against the Maori, we dominated territory and possession, and we squeezed the life out them, an unbelievably talented backline that just went nowhere.
"For Sam, look, we were hoping he was going to be part of the 23 against the Crusaders. Unfortunately he rolled his ankle a little bit so hadn't recovered in time.
"So he had time against the Highlanders and we were able to give him time last night. So there will be some tough debates and discussions to have on the final make-up of what the back-row is going to be for Saturday."
Will there be a pre-match haka?
Yes. The Chiefs rolled out theirs for the first time last year when they towelled up Wales.
It was spectacular then and will be again tonight.
What's our prediction?
The Lions' midweek team are not the same beast as the weekend team. Not that Gatland will care if they lose tonight. But it will dent the overall aura of the Lions. Dave Rennie's Chiefs will be up for this one. Our tip is the Chiefs by 8.
