Crystal Palace F.C. will not rush injured winger Wilfried Zaha back into action and have not put a timeframe on the Ivory Coast international’s return, the Premier League club’s manager Frank de Boer has said.The 24-year-old, who scored seven league goals and provided 11 assists to win Palace’s Player of the Year last season, sustained a knee injury during their 3-0 defeat to Huddersfield Town F.C. in the opening league game of the season.”Wilf is a very robust player, the first couple of days (after the injury) are very important to have a rest and, from now on, I think he’s going to start rehab,” De Boer said after Wednesday’s 2-1 win over Ipswich Town F.C. in the League Cup.

The risk is that you start too early, that he can have a setback, so we are going to see and don’t put a time on it right now.”Palace, who will play Huddersfield Town F.C. again in the third round of the League Cup in September, host Swansea City F.C. in the league on Saturday.
