The San Antonio Spurs have pulled their offer to Marcus Morris and agreed to a deal with free-agent forward Trey Lyles, league sources told ESPN's Adrian Wojnarowski.
Morris will sign a one-year deal with the New York Knicks, sources said.
Morris, 29, averaged 13.9 points and 6.1 rebounds for the Boston Celtics in his seventh NBA season.
The Knicks already signed three power forwards in free agency, including Julius Randle, Bobby Portis and Taj Gibson.
