Here are three takeaways from the loss. Rookies Cedric Coward, Jahmai Mashack and Javon Small all missed the game against the Celtics. Coward hasn't been with the Grizzlies in Salt Lake City or Las Vegas while he continues to get back to full strength recovering from a shoulder injury.

For a player who was not even on the roster for the Sin City Celtics, big man Charles Bassey had an impressive impact.

LAS VEGAS — A balanced effort on both ends of the floor and sharp offensive performances from Jordan Walsh and Charles Bassey powered the Boston Celtics to a 92-78 win over the Memphis Grizzlies in an NBA 2K26 Summer League battle at Cox Pavilion in Las Vegas on Friday afternoon.
