Coach Jason Kidd said the soreness was a residual effect from the left ankle sprain that sidelined Doncic for three games last month. The 22-year-old also dealt with a sprained left knee then. The Mavericks lost all three games without their two-time All-Star.
Doncic showed moments of discomfort Friday in a 107-91 loss to New Orleans, a third straight home defeat. But Kidd said Doncic didn't aggravate the injury. Kidd said Doncic had an MRI but wouldn't reveal the results.
"It's just been a busy stretch of games for us,'' Kidd said. "So we'll see how he feels tomorrow.''
The Mavericks also were without Kristaps Porzingis, Doncic's oft-injured European sidekick, for a second consecutive game because of a left knee contusion. Kidd said Porzingis was injured Monday in a victory at New Orleans.
Center Willie Cauley-Stein missed his fourth consecutive game, the last three of which have been for personal reasons.
Memphis was missing guard Ja Morant for a fourth consecutive game because of a left knee sprain. Morant was the second overall draft pick in 2019, a year after Doncic went third.
The Grizzlies were playing for the first time since setting an NBA record with a 73-point margin in a 152-79 win at home against Oklahoma City.
