Dekker suffered the injury in the third quarter of Monday night’s contest against the Orlando Magic, as the Cavs fell in heartbreaking fashion, 102-100. He actually started the game, but finished with just two points in 14 minutes of action.
The forward is expected to miss two to four weeks of action as he undergoes a period of treatment and rehabilitation.
In addition to Dekker, All-Star Kevin Love is also currently on the sidelines due to a left toe injury. Love underwent surgery earlier this month and will miss at least six weeks of action, with rumors spreading that he could even miss the entire season.
