Walker suffered an undisclosed lower-body injury during Saturday's game against the Suns and was forced to exit, Jeff Garcia of News 4 San Antonio reports.
More information should be available after the game, but Walker looks like he'll finish the contest -- which coincided with his 21st birthday -- with 16 points (5-8 FG, 1-1 3Pt, 5-5 FT), three rebounds and one assist in 21 minutes. The 2018 first-round pick appears to have found a home on the Spurs' second unit, as he's averaging 13.8 points (on 54.2 percent shooting from the field), 3.0 rebounds, 1.2 triples, 1.0 assist and 1.0 steal in 21.6 minutes over the past five games.
