Zou needs more time to recover

Zou Shiming isn't quite ready to toss in the towel.

China's two-time Olympic gold medalist and former WBO flyweight champion has checked out of hospital in Shanghai after being treated for vision problems that threaten to end his boxing career.

The 36-year-old, who lost the world title to Japan's Sho Kimura when he was stopped in the 11th round in his first title defense last July, has had some improvement in his vision but it's too early to say when or if he will return to the ring.
