Mann will start Monday's game against the Cavs, Tomer Azarly of Clutch Points reports.
The Clippers are resting Marcus Morris and Reggie Jackson, so Mann will move into the lineup at one guard spot alongside Amir Coffey, Luke Kennard, Nicolas Batum and Ivica Zubac. Mann had come off the bench in each of the last three games and struggled to be productive, scoring fewer than 10 points in all three.
