If I was an AFC fan, I'd still go to the game, they'd be losing their own club money surely if they didn't bother turning up. I'd turn up full of hatred for MK and sing my heart out.
I've never seen the point in boycotting a game to be honest, and I'll never do it either.
Could well be on the cards, AFC currently 4-2 up in ET against York, whilst MK play tomorrow against Cambridge.
Winners of each tie play each other of course, a game I'd love to see!
