Grizzlies star Ja Morant's mom will NOT be in Utah to watch Memphis take on the Jazz on Wednesday ... after fans made disgusting and racist remarks towards their family earlier in the playoff series.
3 Jazz fans were banned indefinitely for comments made to Morant's parents during Game 2 on May 26 ... with Ja's dad, Tee, telling ESPN the harassment was "straight up disrespectful."
Jazz owner Ryan Smith apologized to the Morants and offered courtside seats, transportation and a hotel to Game 5 for family and friends .
