Ja Morant was listed as "out" by the Memphis Grizzlies for Game 2 of their first-round playoff series against the Los Angeles Lakers.
Morant left the court in Sunday's Game 1 defeat to the Lakers at FedExForum in the fourth quarter after trying to break his fall on a drive with his right hand, with his wrist bending unnaturally.
An MRI on Monday revealed a re-aggravation of soft tissue in his hand, having previously suffered an issue against the Milwaukee Bucks on April 7.
According to multiple reports, the Grizzlies listed Morant out prior to the start of Game 2 in Memphis on Wednesday, citing "right-hand soreness".
The 23-year-old was in excellent form in the regular season, averaging 26.2 points and 8.1 assists per game from 61 appearances.
The Grizzlies are already missing key players Steven Adams and Brandon Clarke for the whole of the playoffs, and will be hoping Morant can return as soon as possible.
