The Lakers originally placed a timetable of 7-10 days on Nash, but that was almost a month ago. The team had an MRI scheduled Monday for Nash but opted to let him go through drills with strength and conditioning coach Tim DiFrancesco to see how he responded.
"I really don't (know when Nash will return)," Lakers coach Mike D'Antoni told reporters. "It's getting better every day. I know we keep saying that, but it is. Just when he's able to withstand some up-and-down, he'll play."
Nash injured the leg in the Lakers' second game of the season when he banged knees with Damian Lillard.
The Lakers are still without their backup point guard Steve Blake, who is out recovering from a strained abdomen. There was some expectation Blake would be returning soon, but he didn't practice Monday and is still listed as day-to-day. Both Nash and Blake have been ruled out for Tuesday's game against the Pacers, D'Antoni told reporters.
