Bill Mueller joined the Dodgers in San Francisco and said there has been little improvement in his surgically repaired right knee.

"It heals as far as living a normal, daily life," Mueller said. "But as far as physical pounding and activity as a major league baseball player, the knee would not be able to withstand that as of right now."

Without another surgery, Mueller's 11-year career in the big leagues could end this winter.
