Toppin (back) is out for Sunday's game against the Nets, Alex Golden of SI.com reports.
After missing Friday's 145-125 loss to the Heat, Toppin will miss his second straight contest due to lower back soreness. Sunday's matchup with Brooklyn is the first of a back-to-back set for Indiana, so the hope is that Toppin will be able to suit up on Monday. In his absence, Jarace Walker and Jalen Slawson should continue earning more minutes off the bench.
