Andy Katz has the story, with video to boot.
"It really flared up during the combine during the vertical tests and the sprinting," said Redick. "I've been pain free. It was asymptomatic. I've been doing exercises to strengthen my back. I'll be back on the court in a week."
A number of teams told ESPN.com that Redick's disk injury caused their team doctors to flag his medical at the Orlando pre-draft camp. Doctors from every team review the medical tests at the camp. Some red flagged him, which would mean not to take him while others yellow flagged him which means to watch his recovery... "I've seen two back specialists and worked with a physical therapist and they don't think surgery is needed," Redick said. "I've had positive feedback. Hopefully I'll play in the summer league which will be a good prep for me for the national team trials."
UPDATE: WebMD on disk trouble and what can be done about it. Seems like degree is the issue. If it's mild, it can go away, if it's not... it might be the kind of thing that would make you want to get trashed and drive around North Carolina.
