This was in the flashcards and I'm not so sure it's the correct translation. "Non merci, j’ai déjà fait du sport avant-hier" is translate (in the flashcards) as "Non thanks, I've already played sports the day before yesterday". I'm confused though. Why would you use fait instead of joué? If this translation is right then why is fait used? Also should sports be translate sport because it's not plural?
