The Knicks have officially waived Chris Smith, the team announced today in a press release. The brother of J.R. Smith was brought aboard to compete for a spot on the roster, but suffered a patella injury that will keep him out for three to six months.
Marc Berman of the New York Post wrote a couple weeks back that there was speculation that one of the stipulations when J.R. signed with the Knicks was that his brother would earn a roster spot. However, following the injury, Chris probably wouldn't have been able to contribute until late in the season, if at all. As such, the Knicks were highly unlikely to use a roster spot on him.
The younger Smith's contract was believed to be fully non-guaranteed, so it shouldn't cost the Knicks anything to waive him. According to Mark Deeks of ShamSports, the contract would have become fully guaranteed if Smith had remained on the roster through November 1st.
