Euro 2008 co-hosts Switzerland have been hit by more injury and illness problems, including the withdrawal of reserve goalkeeper Fabio Coltorti.

Coltorti, 27, reported for Switzerland's 10-day training camp in Lugano yesterday but was sent home after being diagnosed with post-viral fatigue syndrome.

The Swiss FA announced on its Web site (www.football.ch) the Racing Santander keeper would be replaced by uncapped Eldin Jakupovic of Grasshoppers Zurich. Striker Blaise Nkufo also looks certain to miss the tournament after picking up a groin injury while playing for Dutch side Twente Enschede.

The 32-year-old is due to undergo further tests in Lugano today but will "in all likelihood miss Euro 2008", according to the Swiss FA statement. No decision has been announced on a possible replacement for the Kinshasa-born striker, who scored 25 goals for Twente this season.

Swiss hopes of having experienced central defender Patrick Mueller back in the team for Saturday's friendly against Slovakia have been dampened due to an injury to his Olympique Lyon team mate Jean-Alain Boumsong. Lyon have said they would not make a decision over Mueller's availability until tomorrow at the earliest. The Ligue 1 champions are due to play in the French Cup final on Saturday. Mueller still has to prove his fitness to Swiss coach Koebi Kuhn after recently recovering from a cruciate knee ligament injury sustained in December.

Switzerland have already been deprived of playmaker Xavier Margairaz following a cruciate ligament injury while regulars Philipp Degen, Ludovic Magnin, Johann Djourou, Marco Streller and Alex Frei have all missed chunks of the season through injury.

Kuhn is due to select his final 23-man squad for the tournament on May 28. Switzerland are then due to play a final warm-up against Liechtenstein two days later before heading for their tournament base in central Switzerland on June 2.

Euro 2008, which is being co-hosted by Switzerland and neighbouring Austria, runs from June 7-29.
