The Philadelphia 76ers will be without centre Jahlil Okafor and forward Robert Covington for the remainder of the NBA season.
Counting Friday night's battle against the Cleveland Cavaliers, the two starters will miss the last seven games of the regular season.
Philadelphia announced on Friday that Covington's right knee had a slight tear of the lateral meniscus. Okafor is still dealing with right knee soreness.
Okafor, who has not played since March 22 against the Oklahoma City Thunder, really stepped up after the 76ers traded Nerlens Noel away to the Dallas Mavericks, and Joel Embiid was ruled out for the season.
Ben Simmons, the number one pick in the 2016 NBA Draft, missed the entire season, but should be ready to start next term.
