Memphis Grizzles guard Ja Morant Petre Thomas-USA TODAY Sports

Grizzlies star Ja Morant, who’s currently sidelined with a sprained knee, has entered the league’s health and safety protocols, the team announced (Twitter link). Adrian Wojnarowski of ESPN tweets that Morant is fully vaccinated against COVID-19 and has received a booster shot.

It’s not clear if Morant tested positive or not, but if he did, he will be out for at least 10 days or until he returns two negative tests a minimum of 24 hours apart. Being in the protocols could impact his rehab process, but since he was already sidelined, he’s unlikely to miss any extra games.

Morant was in the midst of an outstanding season before the injury, averaging 24.1 points, 5.6 rebounds and 6.8 assists per game on 48% shooting. Despite Morant being sidelined, the Grizzlies have won five games in a row, including a record-breaking 73-point victory over the Thunder.

Memphis faces Dallas Wednesday night. In addition to Morant, the team also listed Brandon Clarke (sore knee), Sam Merrill (ankle sprain) and rookie Ziaire Williams (ankle sprain) as out, with Kyle Anderson (back) doubtful.
