Bargnani has been dealing with the illness for several weeks, forcing him to miss Italy's training camp and several exhibition games. The Italian Basketball Federation released a statement Tuesday saying that while Bargnani's condition has improved, he won't be able to recover in time for EuroBasket when it tips off in Slovenia on Sept. 4.
The loss of Bargnani is a blow to an Italian team already without Danilo Gallinari. Bargnani was Italy's top scorer and rebounder at EuroBasket 2011, averaging 22.8 points and 7.4 rebounds in five games.
The illness shouldn't hamper Bargnani's availability for Knicks training camp in October. The big man will almost certainly miss the team workouts and scrimmages planned for after Labor Day, however, potentially putting him slightly behind schedule.
