Texas first baseman Prince Fielder sat out Saturday's game against Toronto and will also miss Sunday's game because of a stiff neck, the Rangers said, ending his consecutive-games streak at 547.
General Manager Jon Daniels said he hopes Fielder, who had a pain-killing injection Saturday, can play Tuesday at home against Seattle.
Fielder has been playing through the injury for the last few weeks, but the team decided this would be the best route under the recommendation of back specialist Drew Dossett.
"He takes a lot of pride in being there for his teammate and playing every day," Daniels said. "We got to a point where [Manager Ron Washington] and the medical team told him, 'You're not letting anybody down. We want to get your right.'"
Fielder, 30, has batted .247 with three home runs and 16 RBIs in 42 games with the Rangers.
