DENVER -- Dodgers shortstop Rafael Furcal left the first game of Tuesday's day/night doubleheader against the Rockies with a stiff lower back, and was replaced in the starting lineup for the second game by Ramon Martinez.
Manager Grady Little said Furcal felt the injury in Sunday's game against Arizona.
"It tightened up late in the game today," said Little. "It's day-to-day. The guy plays through a lot of aches and pains. This just got too bad late in the game today."
Furcal went 0-for-3 on Tuesday against Jeff Francis without getting a ball out of the infield. The switch-hitting shortstop came into the game 5-for-17 against Francis. Little lifted him in the top of the seventh inning for pinch-hitter Olmedo Saenz, whose home run was the Dodgers' only run in a 3-1 loss to the Rockies.
Furcal missed the first eight games of the season while on the disabled list after spraining his left ankle in a Spring Training collision with outfielder Jason Repko. He's started all but four games since, even though the injury never completely healed.
