Rangers manager Ron Washington said Andrus will not play Sunday against Minnesota, but should be ready for a crucial three-game series at second-place Oakland starting Monday.
Andrus said he felt the spasms when he hit second base. The pain is in his lower back, he said, not in the same area as earlier in the season when he dealt with upper back issues.
"I'm not playing tomorrow for sure," Andrus said. "We'll see how I feel for the Oakland series."
Andrus is batting .314 with 25 runs scored and 18 RBIs since the All-Star break.
