(Portland, OR)  --  The Trail Blazers signed 6-foot-11 center Enes Kanter for the remainder of the season.  He began the season with the Knicks, making 23 starts, but was limited to three games in the 12 games before the trade deadline as the club shopped him around.  They released him last week when they failed to trade him.  Portland will use him as a backup center.  He has appeared in 560 NBA games and has been on three playoff teams.
