Rajakovic added that Poeltl will be on an unspecified minutes restriction.
Poeltl has played in just 21 games this season, and none since a short seven-minute stint on Dec. 21, as he has battled nagging back pain.
However, the Austrian big man has ramped up in recent days, and will get a comfortable landing spot against the Pistons, who will be without suspended frontcourt stars Jalen Duren and Isaiah Stewart following a Monday brawl against the Charlotte Hornets.
Poeltl, 30, has averaged 9.7 points and 7.7 rebounds per game in his limited action while connecting on 64.9 per cent of his field-goal attempts and 58.3 per cent of his free throws.
Rookie Collin Murray-Boyles, who has often filled in for Poeltl as an undersized centre, is out against the Pistons as he manages a right thumb sprain.
Detroit leads the Eastern Conference with a 39-13 record, 5.5 games ahead of the second-place Boston Celtics. The Raptors sit fifth at 32-22.
