Barnes (thumb) has been ruled out of Tuesday's matchup with the Rockets, Johnathan Feigen of the Houston Chronicle reports.

EDGE Analysis

Barnes is dealing with a right thumb contusion and it will force him to sit out Tuesday despite being listed as probable coming in. With Barnes out of the lineup, the Grizzlies will likely shift Jeff Green over to small forward and insert Zach Randolph into the starting lineup at power forward. Barnes remains without a concrete timetable for recovery, but his next opportunity to return will be Thursday's tilt with the Pistons.
