Steve Nash has missed 12th straight games, counting Saturday's contest against the Mavericks.
Nash hasn't missed so many games in a row since 1999 when he sat out 22 due to an ankle injury.
"I've got to get in shape whenever I can," he said. "That's something that's weighing on my mind every day that goes by."
Nash has a small fracture in his lower left leg.
Nash will be reevaluated on Monday.
Nash has only been able to do 12-minute workouts on an elliptical machine as jogging or jumping is now allowed at this point.
"It flares right up right away," he said.
