Nicolas Batum has been diagnosed with chronic tendinitis in his left Achilles and could miss multiple games.
Batum underwent an MRI on Sunday.
The Hornets are seven games out of the final playoff spot in the Eastern Conference with only 12 games remaining in the regular season.
Batum's 17-18 season has been slowed by injuries beginning with an elbow injury suffered in training camp.
Batum is in the second season of a five-year, $120 million deal with the Hornets.
