A bad salad at a German hotel might have caused the food poisoning that sickened 10 players of European Championship co-host Ukraine before their final warm-up game against Turkey on Tuesday.

Ukraine team doctor Leonid Mironov believes the weakened players suffered from ''the bad effects of eating a salad,'' the Interfax news agency reported Thursday.

Team spokesman Oleksandr Glyvynskiy told The Associated Press there will be no further investigation into the cause of the food poisoning, despite head coach Oleg Blochin suggesting on Ukrainian TV that ''it may have been sabotage.''

Glyvynskiy said all players had recovered well and the full 23-man squad was expected to complete a training session Thursday, four days before the team's Euro 2012 opening game against Sweden.
