Ajax midfielder Christian Eriksen is likely to play in tomorrow night\'s KNVB Beker match against AZ Alkmaar despite suffering an injury in training today. The Denmark international left the session early after turning his ankle, casting doubt over his participation in tomorrow\'s last-16 tie with the Eredivisie leaders. Ajax manager Frank De Boer immediately played down concerns, though, claiming that, while he would take a cautious approach with his star man, Eriksen was fit enough to play. \"It\'s not serious, but we will not take risks with him,\" De Boer said. \"The probability that he plays is 95 per cent.\" Eriksen\'s likely inclusion is good news for Ajax who are set to rest Siem de Jong, after he recently returned from a hamstring complaint, and Vurnon Anita, who has suffered a mild concussion.
