Braves' outfielder Mark Kotsay says that his back spasms haven't improved over the last nine days and that there is no timetable for his return, according to The Atlanta Journal-Constitution.

"It's day-to-day," said Kotsay, who hasn't played since May 25. "We're doing all the necessary treatments, trying to get me back as soon as possible. It's a mental grind. I'm sure everybody's wondering what's going on."
