Nash, a two-time NBA MVP, participated in a full practice session with the Lakers on Thursday.
After recently ruling out Nash's return, Lakers coach Mike D'Antoni changed course on Wednesday and suggested Nash could return over the final 15 games of the regular season.
Nash, 40, has suffered from nerve damage in his back and hamstring injuries this season. Nash, who hasn't played a game since Feb. 11, has averaged 7.6 points and 4.7 assists in 10 games.
Nash has one year left on his three-year deal and insists he'll return next season to collect the $9.7 million owed him.
