Xavier Paul, the most likely replacement for Ramirez, was removed from Friday night's Triple-A Albuquerque game after six innings. Paul is hitting .348.
The 38-year-old Ramirez was out of the starting lineup for a second consecutive game in Friday's 12-5 loss to the D-backs and was replaced by Garret Anderson in left field. Although he told manager Joe Torre his leg felt better, Torre wasn't sure that was enough.
"We have to find out what good is and what that gets him and us," Torre said. "We have to figure out if it's worth playing one man short."
Torre said Ramirez was not available to pinch-hit Friday night and probably would be unavailable the entire weekend. Ramirez injured the leg running the bases in the first inning Tuesday night, so he could be disabled retroactively to Wednesday.
"We don't know to what degree it will get better, and what it gets the team and what he can offer the team," said Torre. "Is he a player by Tuesday, or a pinch-hitter by Monday or Tuesday? We have to decide if it's worth playing a man short."
