After officially announcing the signing of Justin Brownlee on Monday, the Knicks have already waived their 20th man, according to the team (Twitter link). In Brownlee's place, New York has signed Chris Douglas-Roberts to fill out the preseason roster.
Douglas-Roberts, 26, participated in camp with the Lakers and Mavs a year ago, and eventually appeared in a handful of regular season contests for Dallas. However, the 6'7" wing hasn't seen significant NBA minutes since he played for the Bucks in the 2010/11 season. As Adam Zagoria of SNY.tv notes (via Twitter), Douglas-Roberts becomes the latest in a long line of CAA clients to join the Knicks.
The Knicks' motives for cutting Brownlee so early in camp aren't entirely clear, though Ian Begley of ESPNNewYork.com (Twitter link) is hearing the St. John's product may have sustained an injury. In that case, it makes sense that the club would want to bring in a healthy body.
