Bayern Munich striker Luca Toni is doubtful for his side's clash with Hamburg in the Bundesliga due to a hamstring injury, the club said. Toni limped off the pitch during his side's 3-0 victory over Hannover over the weekend but coach Ottmar Hitzfeld played down the importance of the injury. “It is not too serious, he needs between seven and ten days of rest,” the veteran manager told the club's website. Toni scored three times in as many appearances with Bayern since joining from Fiorentina in the summer. The injury might also force Toni out of Italy's game with France in the Euro 2008 qualifiers next week.
