So this is a Wikipedia article right.. But this is the copy of the Wikipedia article BEFORE the person died. Click on view original and you will see "was a Columbian football player" rather than "is". Just a bulletin for Duolingo to periodically update the page that contains what we are translating, especially if it is Wikipedia.
