FEUSISBERG, Switzerland, May 25 (Reuters) - Switzerland coach Koebi Kuhn has recalled Young Boys Bern midfielder Hakan Yakin from his holidays as an increasingly likely World Cup replacement for injured striker Johan Vonlanthen.
Speaking in a press conference at the Swiss team's training camp on Thursday, Kuhn said Yakin's inclusion was not yet official although team doctors now say that Vonlanthen could be out of action for at least a month.
The 20-year-old NAC Breda forward partially tore a hamstring during training on Monday, although the extent of the injury was only revealed by an MRI scan the following day.
"I won't be making any change to the squad just yet," Kuhn said. "But the plan is to have Hakan Yakin back with us by Friday at the latest and possibly on the teamsheet for Saturday's friendly against Ivory Coast.
"Johan will stay with us for now, though, and we will see how he does over the next few days."
Coaches are able to replace injured players up to 24 hours before their first World Cup match -- in Switzerland's case, against France on June 13.
Kuhn was again asked on Thursday about his original decision to leave Yakin out of the squad and about questions he raised at the time over the former Basel playmaker's character.
"I think the issue has been a little simplified," Kuhn said. "What I said was that certain aspects of Yakin's character could raise questions when it comes to the existing life of the team.
"I may well need to talk to him about it when he arrives, but I think he has already learnt his lesson."
Switzerland also play South Korea and Togo in Group G.
