Although Turner will be re-examined in two weeks, ESPN's Adrian Wojnarowski is reporting the injury is expected to keep Turner out of action past the NBA's trade deadline on Feb. 10.
Turner was a surprise scratch from the lineup prior to Monday's 139-133 loss to the Los Angeles Clippers for what was believed to be a sore left ankle/foot.
The 25-year-old Turner, who is in the final season of a four-year contract, is averaging 12.9 points, 7.1 rebounds, 1.0 assists and a team-leading 2.8 blocks per game. He led the league in blocks during the 2018-19 and 2020-21 campaigns.
Indiana, which has lost four straight, is likely to be a seller at the trade deadline sitting 13th in the Eastern Conference with a 15-29 record.
