The Lakers (24-46) visit Milwaukee on Thursday night, with a chance to win their third-straight game.
The Bucks defeated the Lakers on Dec. 31, 94-79, getting 37 points from guard Brandon Knight.
The Lakers had no answer from the third-year guard, who shot 15 for 25 from the field along with eight rebounds and four steals.
On the season, Knight is Milwaukee's leading scorer at 17.4 points a night, along with 4.9 assists.
Marshall is averaging 8.2 points and 9.0 assists a game, but Jodie Meeks (15.3 points a night) may get the primary defensive assignment on Knight.
The Bucks have an interesting rookie in Giannis Antetokounmpo. While he's not a big scorer (7.0 points a night), he's already a strong defender and impressive athlete.
Against the Lakers in December, Antetokounmpo scored eight points with 11 rebounds.
Xavier Henry has been playing well for the Lakers. On Tuesday, Henry scored 22 points off the bench against the Knicks, despite a recently torn ligament in his (left) shooting wrist.
The Bucks have improved offensively in recent weeks, despite their losing streak.
Chris Kaman will start for Gasol in a winnable game for the Lakers.
