Spoiler

Natsu had eaten Etherion and entered Dragon Force mode. Jellal was about to use Abyss break but Erza had slashed and as he was about to use it the injury stopped him and before he had time to recover Natsu punched him through the tower and knocked him out. I would say it didn't really count as if Natsu eaten Etherion Jellal would have won.
