Memphis Grizzlies rookie Ja Morant did not travel with the team to Minnesota for Sunday's game and is listed as week-to-week after experiencing aggravated back spasms in the Grizzlies' 103-94 loss to the Utah Jazz on Friday night.

Memphis said the guard needs a "period of short-term off-loading" in a statement on Saturday. Morant first experienced back spasms against the Pacers on Monday night.

The rookie is off to an impressive start to his NBA career, averaging 18.6 points and 6.4 assists in 28.7 minutes per game this season.
