What happened: Miami Heat announced guard Norman Powell is out for Saturday's game at Houston Rockets due to calf tightness that arose this morning. Coach Erik Spoelstra noted Powell couldn't loosen it up and will be evaluated daily. He joins Jaime Jaquez Jr. (hip) and Andrew Wiggins (toe) on the sidelines.

Why it matters: The Heat, sitting at 38-32 and battling in a tight Eastern Conference playoff race, could tie for sixth with a win if Orlando loses. Powell accounts for 19% of Miami's points, and the team will miss 47% of scoring, 33% rebounds and 39% assists without their injured players.

What to watch: Monitor Miami's opening lineup featuring Tyler Herro, Bam Adebayo, Pelle Larsson, Davion Mitchell and Simone Fontecchio; watch for updates on Powell's status ahead of next games in playoff push.
