Iwundu isn't starting Monday's game against Portland, Brad Rowland of PeachtreeHoops.com reports.
Iwundu drew a spot start Friday night against Cleveland, but with Atlanta gaining a number of players back from the league's health and safety protocols, he'll head back to a reserve role. He's logged 23 and 16 minutes in his two games off the bench this season, scoring 10 total points and tallying seven boards over that brief stretch.
