McDermott's ankle sprain has been diagnosed Grade 3, and he's expected to sit out the rest of the regular season, independent NBA writer Matthew Tynan reports. Assuming the timeline holds, McDermott will conclude his debut season with the Spurs averaging 11.3 points, 2.3 rebounds and 1.3 assists in 24.0 minutes. He, as usual, shot well from distance, drilling a career-high 2.1 threes per game at 42.2 percent. In McDermott's absence, coach Gregg Popovich figures to hand more minutes to Josh Richardson, Lonnie Walker, Keita Bates-Diop (back) and Romeo Langford (hamstring). The Spurs are only two games back from the 10-seeded Pelicans, so it's still possible they make the play-in games and McDermott comes back.
