"Al Harrington will undergo season-ending shoulder surgery tomorrow in and likely has played his last game as a Knick.
Harrington, the Knicks' sixth man, will be a free agent and decided to get a jump on summer. Harrington said last week he would delay arthroscopic surgery on his AC joint until after the season.
But because he needs to go through 3-4 months of rehab and will be a free agent, Harrington elected to get it over with it now with five games left in the season and the Knicks are playing out the string."
