Poeltl (back) has been ruled out for the rest of Sunday's game against the Nets, Vivek Jacob of the Raptors' official site reports.
Poeltl was cleared to return Sunday after a two-game absence due to a back injury, but he appears to have aggravated the issue during the first half. Sandro Mamukelashvili should start the second half and see a significant increase in playing time during Poeltl's absence. Poeltl will finish the contest with two points (1-1 FG), two rebounds and a turnover in seven minutes.
