<p>MIAMI — The San Antonio Spurs do not expect starting guard Derrick White back this season because of a sprained right ankle, coach Gregg Popovich said Wednesday.</p>
<p>White was injured in the Spurs’ win in Washington on Monday. The fourth-year guard is averaging a career-best 15.4 points this season for San Antonio, which played 18 of its first 19 games this season without White because of a toe injury.</p>
<p>“You can imagine, his spirits are not high," Popovich said.</p>
<p>San Antonio was at Miami on Wednesday night.</p>
<p>White is not expected to require surgery. Rookie guard Devin Vassell will take White’s place in the starting lineup, Popovich said.</p>
<p>“When he gets minutes, he’s played well," Popovich said of Vassell.</p>
<p>White has averaged 10.8 points in 188 games over his four seasons in San Antonio. He’s been the Spurs’ third-leading scorer this season behind DeMar DeRozan and Dejounte Murray.</p>
