"Rafael Furcal will make the move he resisted. He is heading to the 15-day disabled list.
On his way out of the Dodgers' clubhouse Tuesday night, Furcal said his surgically repaired lower back stiffened in a pregame workout, which included fielding grounders at shortstop.
Furcal hadn't fielded grounders since he strained his back on a throw across his body Aug. 2.
"We decided it was probably the safest thing to do," Manager Joe Torre said.
Torre said the decision was made during the game Tuesday night.
"It's not a setback," Torre said. "He got loose, but when push comes to shove, with a week invested and a week to go, it's probably smarter to do this."
Furcal will be eligible to be activated Aug. 17 for the start of the Dodgers' next homestand."
