The Knicks waived four players to get down to the 15-man roster limit today, cutting ties with Oscar Bellfield, John Shurna, Mychel Thompson and Henry Sims, as Jeff Zillgitt of USA Today reports (Twitter link). Shurna and Sims had partial guaranteed of $50K, while Bellfield's and Thompson's contracts were non-guaranteed. The moves likely mean Chris Copeland, who has a non-guaranteed deal, will be on the Knicks opening-night roster.
