There's a ton of history between AFC Wimbledon and Milton Keynes Dons. MK Dons began life as Wimbledon, before a controversial move brought a new name—and left Wimbledon without a team. A year before the move, fans started their own club, and AFC Wimbledon has achieved five promotions over the last nine seasons. But going into their second round FA Cup tie, the two teams had never met.
MK Dons, in League One, triumphed over League Two side AFC Wimbledon, but it was damned close. It relied on this injury time backheel from Jon Otsemobor, just about the most nonchalant heartbreaker you'll see.
