The Lakers, left with only one healthy point guard, are planning to use Nash as a backup to Kendall Marshall against the Washington Wizards at Staples Center.
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.
D'Antoni informed reporters that guard Nick Young and forward Jordan Hill would return from injuries on Friday, too. The Lakers lost point guard Jordan Farmar to an injury this week.
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.
