JAYSON WILLIAMS RELEASED FROM RIKERS!

Disgraced former NBA superstar Jayson Williams is a free man again -- the 44-year-old was officially released from Rikers Island jail this morning.

Williams completed 8 months of his 1-year sentence ... stemming from a DUI arrest in 2010.

TMZ broke the story ... Jayson's blood alcohol level was .24 -- 3 times the legal limit -- and cops say he swerved across four lanes of traffic before striking a tree in NYC.

Before his stint at Rikers, Williams served 18 months in Wrightstown, NJ for aggravated assault and obstructing justice ... as part of a plea deal he accepted in the 2002 shooting death of his limo driver.
