The Boston Celtics are right back to playing shorthanded. After routing the Los Angeles Lakers at home with a fully healthy squad, the Celtics will host the Memphis Grizzlies on Wednesday night without Jaylen Brown, who sprained his ankle Monday. Brown's absence may pose an issue for Boston against a red-hot Grizzlies team led by dynamic young stars Ja Morant and Jaren Jackson Jr. that has won seven of its last eight games.
