Kiwi Steven Adams has been ruled out of NBA action for up to five weeks after suffering a posterior cruciate ligament (PCL) injury in his side's defeat to Phoenix Suns on Monday.
Memphis Grizzlies centre Adams, 29, has been given a prognosis of missing between three and five weeks after the injury suffered in his right knee.
Adams missed the Grizzlies' 133-100 defeat to Sacramento Kings on Tuesday with what was initially labelled as "knee soreness", before the team confirmed the extent of his injury on Wednesday.
So far this season, Adams has averaged 8.6 points per game, to go with 11.5 rebounds, 2.3 assists and 1.1 blocks across his 42 games played.
Despite sitting second in the NBA's Western Conference, the Grizzlies are currently on a three-game losing streak, with Adams' absence to hit the team hard.
The Grizzlies return to the court on Thursday, when they travel to face reigning NBA champions Golden State Warriors.
