Bates-Diop will start Monday's game against the Suns, Jeff McDonald of the San Antonio Express-News reports.
Bates-Diop has played only 12 minutes in three games since returning from a back bruise, but he'll start Monday with Doug McDermott (knee) sidelined. Bates-Diop has averaged 3.0 points and 2.9 rebounds in 12.5 minutes through 11 games this season, though he may see more playing time versus Phoenix.
