New Memphis Grizzlies stud Josh Jackson just caught a break in his resisting arrest case ... TMZ Sports has learned he just copped a plea deal and will likely have his case dropped.
Jackson was arrested at the Rolling Loud Music Festival in Miami, Florida back in May after cops say he entered a VIP area without proper credentialing.
Cops say when he refused to leave ... they cuffed the 6-foot-8, 200-pound NBA player and put him on a golf cart.
But, police say Jackson got up and walked away ... and when cops told him to stop, he started running.
