The New York Yankees have placed Kevin Youkilis on the disabled list with a lumbar spine sprain.
Youkilis had missed eight of New York's past nine games with the persistent back issue.
"It was just one of those things waking up, and I didn't feel right," Youkilis said. "Sometimes, after your adrenaline's gone, things occur to you. We've just got to find out what's going on."
