Jorge Posada will be the DH tonight and hopes to catch tomorrow, but he said that the cyst behind his left knee is just one of those things that catchers endure as they squat and stand pitch after pitch, inning after inning, year after year.

"It's going to be there. It's OK to DH," he said a few minutes ago. "It has been there for a while. Catchers get that." He said that it flared up over the past week.

"It has been there since '06, that was the first time I felt it. They haven't done anything. You just deal with it. I've got to heat it before the game and get it loose, once I get it loose, I'm fine.

"I really can't tell you when it happened, how it happened," he said. "We've just got to keep treatment and get it better. There's not a specific thing that I do."
