Grizzlies star Ja Morant is being sued over an alleged fight with a 17-year-old. TMZ Sports says the lawsuit was filed last September, and alleges that Morant punched the teenage victim during a pickup basketball game at his Tennessee home, after the teen threw a basketball at Morant's face. Police reports say Morant admitted to striking the teen, but said it was in self-defense. He also told police his brother was involved in the altercation.
