Vassell will start Sunday's game against the Kings, Paul Garcia of ProjectSpurs.com reports.
Vassell will be making a spot start Sunday in place of Doug McDermott, who is out with a tooth infection. The 21-year-old will be making his first start of the season and will be playing at the 4 while presumably switching Keldon Johnson to the 3. The Spurs can afford to play a bit smaller with the Kings starting 6-9 Tristan Thompson at center. Vassell has averaged 11.2 points, 3.8, 1.4 assists and 1.1 steals in 24.3 minutes per game so far this season.
