Mathurin will start Monday's preseason game against the Grizzlies.
With Tyrese Haliburton and T.J. McConnell resting, Andrew Nembhard will shift to point guard, while Mathurin enters the starting lineup at shooting guard. Last Thursday, Mathurin exploded for 25 points (8-12 FG) in 19 minutes off the bench during a win over the Cavaliers.
