After spending the past 16 days behind bars … Jalen Rose is a free man!

According to TMZ, Former NBA star Jalen Rose was released from a Detroit jail this morning — after spending 16 days behind bars stemming from a DUI arrest back in March.

Rose — who currently works for ESPN as an NBA analyst — was originally sentenced to 20 days in the slammer … after pleading guilty to driving while intoxicated during a March 11 crash.

TMZ broke the story … the 38-year-old ex-Fab Fiver was driving along an icy roadway in Michigan with a female passenger when he lost control of his vehicle, flipping the car.

After the judge basically threw the book at Rose — Jalen’s lawyer called the sentence “outrageous” … and an “abuse of discretion.”

Nice to have you back on the outside, JR!
