Detroit Lions star Jameson Williams' Thanksgiving week is off to a good start ... he just learned he will not face criminal charges over that controversial traffic stop he was involved in last month.
Wayne County Prosecutor Kym Worthy said in a statement to TMZ Sports on Monday she is denying the Detroit Police Department's request for a warrant for Williams' arrest ... after "a team of experienced lawyers" looked over his case thoroughly.
"We all agreed that this decision is the right and just one," she said.
