Doha (Qatar ExxonMobil Open) 2012:
QF: Roger Federer def. Andreas Seppi 6-3, 5-7, 6-4
R2: Roger Federer def. Grega Zemlja 6-2, 6-3
R1: Roger Federer def. Nikolay Davydenko 6-2, 6-2
Roger withdraws before his semi-final match against Jo-Wilfried Tsonga with a back injury.
“I hurt my back in my second-round match against Zemlja and just got a little bit better for the match against Seppi,” said Federer.
“I don’t feel a whole lot of improvement for today, and I just don’t think it’s the right time to risk anything more right now. I still have pain, and that’s why it was the only right decision, a difficult one for me.”
"For Australia, I’m optimistic, just because it’s not very good but it isn’t crazy bad," Federer said. "I have had bad backs in the past. This is definitely not very good; otherwise I would be playing. But I feel without play and the right treatment, I will get through it in the next few days."
