The Knicks had interest in bringing back Clippers point guard Darren Collison and rookie Reggie Bullock as part of a package, but wanted Los Angeles to accept Raymond Felton in the deal, sources said. The Clippers resisted the Felton element of the deal, and were reluctant to part with Bullock or any draft picks in talks, sources said.
Clippers general manager and coach Doc Rivers has been determined to upgrade athleticism on the wings and sees Shumpert as a player who can complement JJ Redick and Jared Dudley. Redick is expected to miss a month with a back injury.
Shortly after talks broke down, Shumpert had to leave the Knicks' game against the New Orleans Pelicans with a sprained left knee. He did not return to the game, and the severity of the injury was immediately unclear.
The Knicks are still interested in pursuing a point guard before the Thursday trade deadline, but are running out of possibilities. New York has tried to stay aggressive in pursuit of Toronto's Kyle Lowry, but the Raptors have turned down recent offers around that NBA that have included packages of a starting point guard and future first-round picks.
