Go and have that pint, Staffan!
For those who can't grab an early cut, we'll get Geoffrey Boycott's thoughts on the day shortly...
Earlier we asked you for your questions for injured fast bowler Mark Wood. You didn't disappoint.
Charlie Godden - Other than cricket, what sports do you love playing?
Anything going. Squash, badminton, football, I even had a go at rugby, but I tried to tackle a bloke nicknamed Shrek once, and he flattened me. So that was my last game of rugby. I love boxing and Conor Mcgregor in the UFC.
Maxi Kelly - Who's the worst footballer in the team? In the coaching staff, it's Ottis 'gammy knee' Gibson. As a player, I'm going for Adam Lyth, because he never passes.
Who are the players likely to emerge for South Africa?
BBC Test Match Special
"South Africa have three inexperienced seamers in this game but they need to look at the next top-order batters. Dean Elgar has stamped his authority on one slot but they need to find the next generation.
"Selection and leadership are crucial now and they need a strong coach to identify the players to move the team forward."
Did you overreact when Finn clipped the stumps?
BBC Test Match Special
"I just raised that it was off-putting. I didn't raise a fuss behind the scenes but mentioned it to the umpires and it was up to them to make the decision.
"He's been outstanding in this series with his pace, and he's got the outswinger going too."
To answer your question, Staffan, we don't know! We think the cut-off time will be 15:30 GMT. The covers are coming on so it's not looking good.
Perhaps go for a Friday pint and follow via the BBC Sport app?
See what I did there? Oh, and mine's a lager.

Staffan Vowles: Any chance of any more play, or can I safely leave work and go for a Friday pint?
Earlier we asked you what Dennis Amiss had in common with Julie Walters, Joan Armatrading, Chris Tarrant, Trevor Francis and The Archers.
Well done to Sean Ranson and Simon Richardson who got the answer...
They've all been awarded a place in Birmingham's Walk of Stars. Amiss has just had his name added to the pavement in Broad Street.
(Other names underfoot include Lenny Henry, Ozzy Osbourne, Jasper Carrott, Noddy Holder, Murray Walker and Frank Skinner).
Amiss was born and brought up in Birmingham, and scored 102 centuries in 658 first-class matches before he retired in 1987, going on to serve as an England selector.
Who was your favourite opening partner?
BBC Test Match Special
"Herschelle Gibbs was an instinctive player, right-handed too, and I think our styles complemented each other. He took the game on and took pressure off me. Neil McKenzie was a great character with a great sense of humour. And then Alviro Petersen came in and performed well."
In case you missed it earlier, Mohammad Amir was booed on his return to international cricket after a five-year ban, but took a wicket as Pakistan beat New Zealand in a Twenty20 match.
Amir, 23, was playing for Pakistan for the first time since his suspension for spot-fixing ended.
Pakistan beat their hosts by 16 runs to take a 1-0 lead in the three-match series, with Mohammad Hafeez scoring 61 as they reached 171-8.
Amir opened the bowling, taking 1-31 from four overs, but did not bat.
More on that here.
Which bowler used to try to wind you up the most?
BBC Test Match Special
"Jimmy Anderson was always the grumpiest. We had a lot of battles and I used to find ways of irritating him by tapping on his follow-through marks because I felt he got too close to the wicket. He used to go back to his mark muttering away."
Alan Peevers: I haven’t seen The Lion King. You’ve spoiled it for me now.
Did you get annoyed at being described as an ugly batsman?
BBC Test Match Special
"I didn't see myself as stylish like Kallis or De Villiers but I scored runs as an opening batsman. That was my job and I guess there's a few people that would like to be as ugly and effective as me with the bat."

David Payne: For Joel Fentem; no need to check Joe Root's passport, he's not English, he's from the People's Republic Of Yorkshire. Ask Geoffrey.
Here's a question. What does Dennis Amiss have in common with Julie Walters, Joan Armatrading, Chris Tarrant, Trevor Francis and The Archers? We'll answer in a while....
Do you enjoy your status as an England-captain slayer?
Graeme Smith
Ex-South Africa captain on BBC Test Match Special
"I get asked about that a lot. I don't take pride in others' disappointments. It's just how it happened in those series with the build-up in pressure in home Tests.
"Nasser Hussain tried to put me under the pump and I didn't think too much about it because I was only 22, but Michael Vaughan's resignation resonated with me because I was a more experienced captain by then. And then there was Strauss in 2012 at Lord's when he resigned."
Test Match Special are using the delay to put some of your questions to former South Africa captain Graeme Smith. They're coming up now - as are some of your Q&As you submitted for Mark Wood earlier.

Lee Eagling: Stokes and Root together - the bowlers get Stooted around the park.
