Costa Rica is expected to revert to the same side that beat Italy in their second group game, BBC reports.
That would see experienced centre-back Michael Umana and left-sided midfielder Christian Bolanos come back in for Roy Miller and Randall Brenes.
Greece captain Kostas Katsouranis is available once again, having been suspended for the Ivory Coast match.
Goalkeeper Orestis Karnezis looks to have shaken off a knock, but Panagiotis Kone is out injured.
Greece coach Fernando Santos: “We have to pay a lot of attention in this game, they came out top in the ‘Group of Death’.
“As a result we cannot allow ourselves to underestimate them.”
Costa Rica defender Michael Umana: “To have qualified top of the group makes us proud
“It gives us great satisfaction as a group. We have grown as a team although we have always been characterised by strong and silent work.
