NEW YORK (AP) -- Spurs forward Stephen Jackson has left San Antonio's game against the Knicks after spraining his right ankle when he crashed into a waitress working the sideline in front of New York Mayor Michael Bloomberg.

Jackson was hurt in the first quarter Thursday night when he shot a 3-pointer from the corner. The shot missed and he stepped backward out of bounds and onto the waitress, who was kneeling in front of courtside seats.

It was unclear if the waitress was serving Bloomberg, who was seen eating a box of popcorn shortly after the play.
