The Cleveland Cavaliers will be without Max Strus as well as Donovan Mitchell as they take on the Boston Celtics on Tuesday.
Cleveland had already been without Mitchell for the past two games due to a left knee bone bruise, and he is to miss at least the next three.
Strus, who had started every game this season, will join his team-mate on the sideline as the Cavaliers take on the Eastern Conference leaders.
The 27-year-old guard, in his first season with the Cavs, has sustained a right knee strain.
Cleveland follow Tuesday's home game against Boston by visiting the Atlanta Hawks the following night.
The Cavs are third in the East but enduring a sticky patch, 5-5 across their past 10 games and slipping behind the second-placed Milwaukee Bucks.
