National team coach Hernan Dario Gomez was forced to draw up contingency plans in case Delgado could not get fit in time.
Now he can sleep a little easier.
His key striker may struggle for match fitness, but should be able to make some contribution to Ecuador's campaign.
'El Tin' Delgado is worth gold to his country, as was clear on the recent tour both in his presence and in his absence.
The big man was rested against Atletico Madrid earlier this week.
Ecuador dominated the game, carved out a procession of chances and were beaten 2-1.
