Ajax have suffered a major injury blow ahead of the second leg of their Champions League quarter-final against Juventus.
Influential midfielder De Jong walked down the tunnel clutching the back of his leg inside the opening half hour of Saturday’s Eredivisie game, which Ajax led 1-0 through Klaas-Jan Huntelaar.
Dusan Tadic and Huntelaar added further goals before half-time but the bigger picture is not so rosy, with De Jong now looking a likely absentee for Tuesday's trip to Turin.
Erik ten Hag’s side claimed a 1-1 draw at the Johan Cruyff ArenA this week, with David Neres cancelling out Cristiano Ronaldo's first-half opener.
Netherlands international De Jong established himself as one of the most sought-after midfielders in world football thanks to superb performances for club and country, and the 21-year-old will join Barcelona at the end of this season in a deal worth €86million.
