Patrick Ewing Jr. has failed again to stick with his father's old team.

The New York Knicks waived Ewing yesterday, the second time in three years they made the son of the Hall of Famer player their final roster cut.

The Knicks cut Ewing near the end of the 2008 preseason, then signed him to a free-agent deal this summer. However, he averaged just 1.8 points and 6 minutes in four exhibition games and the Knicks instead kept swingman Shawne Williams, trying to rebuild his career after off-court trouble in three previous NBA stops.

Patrick Ewing is the Knicks' career scoring leader.

The Knicks also exercised their fourth-year options on the contracts of Danilo Gallinari and Anthony Randolph, and the third-year option on guard Toney Douglas.

Gallinari, a 6-foot-10 forward, was taken sixth in the 2008 draft. He has averaged 12.8 points and 4.2 rebounds in his first two seasons. Randolph was taken eight picks later by Golden State and came to New York in July in the sign-and-trade deal for David Lee.
