Slumping catcher Carlos Santana has been dealing with a sore right rib cage for the last several days. Things may have taken a turn for the worse Wednesday at Yankee Stadium.

Santana, starting at DH, was lifted for pinch-hitting Lonnie Chisenhall in the ninth inning. After the 5-4 loss to the Yankees, manager Manny Acta said Santana's back tightened and forced him out of the game.

"Carlos has some mid-back tightness," said Acta. "Our medical people said he tested OK. We'll have to see how he is Thursday and how he react to the flight [to Baltimore]."
