Inter Milan star Eriksen suffered a heart-attack in Denmark's loss to Finland in their opening group.
Eriksen is now in recovery and will have taken much pleasure from Denmark qualifying for the last-16 with a 4-1 win over Russia.
Christensen hammered in Denmark's third goal with a rasping long range strike.
After scoring Christensen held up his hands and made the 10 symbol, the number Eriksen has donned for Denmark since 2014.
The Danes will face Wales in the last-16 at Amsterdam Arena on Saturday.
