Rusty Simmons of the San Francisco Chronicle reports:

Monta Ellis back pain began in high school

Guard Monta Ellis revealed Wednesday that he was born with a small hole at the base of his spine, a condition that he says started causing back pain in high school and still is a problem periodically.

The Warriors said the condition is called spondylolysis, a defect that occurs in up to 6 percent of the population and one that doesn’t cause future concerns for the team.

Ellis was immobilized for the better part of the past 12 days but is “leaning” toward playing tonight. “Sometimes it bothers me, but not to the point where I can’t move.”
