Jackson left Friday's 117-105 loss to the Los Angeles Lakers late in the second quarter after an awkward fall when he was contesting a shot. He didn't return for the second half.
He ranks second on the Grizzlies with 16.9 points per game and leads the team with 1.6 blocks per game. Jackson, the fourth overall pick in the 2018 draft, is shooting 39.7% from 3-point range.
The Grizzlies (28-28) currently hold the final spot in the Western Conference playoff race, with a 2½-game lead over the Portland Trail Blazers and San Antonio Spurs for that spot entering Sunday's action.
