Alex Rodriguez said he was "a little sore" after leaving the Yankees' 5-2 victory over the Rangers on Saturday with lower back stiffness.
The three-time American League MVP, who is batting .385 with four home runs this season, was replaced at third base by Eric Chavez for the seventh inning with the Yankees leading 3-0, MLB.com reported.
He later said some pre-game discomfort had become progressively worse in cold conditions.
"I feel OK. I'm a little sore," Rodriguez said. "I had a little knot right in my oblique and just couldn't get warm in this weather."
"I felt it more on [my] swings," he added. "I was swinging weakly, just trying to protect it a little bit. Hopefully tomorrow [Sunday] we'll get a little better weather."
Yankees manager Joe Girardi said Rodriguez would likely not play Sunday against Texas if he continued to feel discomfort.
