You can catch up with Matthew Henry's match report. If you're a Scotland fan, then it might not be the most cheering bit of writing.
We'll be back tomorrow, when South Africa take on West Indies and Pakistan face New Zealand.
Until then!

Also, this was the moment of the day by far.

What a day for Afghanistan, who batted ad bowled brilliantly.

Afghanistan captain Mohammad Nabi: "This was our plan that we win the toss and put a big score on the board.
"The world knows that Rashid and Mujeeb are world-class bowlers. That's why we have the best here. It's a really nice team. It's a very good combination.
"Mujeeb played his first World Cup game and he got the man-of-the-match award. It's fantastic."

Afghanistan are just a quality line-up. We can expect Rashid Khan and Mujeeb Ur Rahman to turn out similar performances. Scotland have just been found wanting today.

Scotland are next in action against Namibia on Wednesday, while Afghanistan take on Pakistan on Friday.
Scotland captain Kyle Coetzer: "Clearly it wasn't one of our better days. We have played some good cricket to get to this stage and sometims things don't go to plan. This is a real sighter for us to say this is what the level is going to be. Afghanistan bowled fantastically well. I think we will be better for this, going into the next game."

It's about exposure and this tournament has done that. They're an intelligent bunch and a dedicated bunch - and there's a lot of cricket left. It's about learning, it's about building and it's about moving forward.

Even if Scotland don't win another game in this tournament, this has been a huge turning point for Scotland, hasn't it?

Player of the match Mujeeb Ur Rahman, who took 5-20: "This was the first World Cup match for Afghanistan. The fans give us positive energy and that's why we're playing positive cricket."

I've loved watching Afghanistan play.

What an absolutely lovely moment - Rashid Khan is chatting to fellow leg-spinner Chris Greaves about the ins and outs of bowling.

Afghanistan are five or 10 years down the line from where Scotland are.

Mujeeb was the star of the show with 5-20, while Rashid Khan has a frankly ridiculous 4-9 to his name.
Only three Scotland batters reached double figures - and two of those were the openers.

There was only one catch in the innings. Everything else was lbw or bowled.
