Nash, who suffered a lower-leg contusion Wednesday against Portland, is listed as day to day.
"He didn't do anything this morning," Brown said. "He didn't do anything yesterday neither."
Nash was injured in the second quarter in Wednesday night's 116-106 loss. He attempted to come back at the start of the third quarter, but quickly retreated to the locker room and did not return to the court.
"They'll give him treatment probably tonight and then we'll re-evaluate tomorrow," Brown said.
