Nesmith will start Monday's game against the Raptors, Brian Robb of The Springfield Republican reports.
The 22-year-old will make his third start of the season with Jayson Tatum (knee) and Jaylen Brown (knee) both out on the second night of a back-to-back set. Nesmith has averaged 7.5 points and 3.3 rebounds over the seven games in which he's played at least 20 minutes this season, so he's not a risky streaming option even with Boston short-handed.
