Vince Young says he's taking "full responsibility" for his drunk driving arrest this week -- and it sounds like he's about to check into rehab to clean himself up.
TMZ Sports broke the story ... the former NFL star was arrested around 4 AM in Fort Bend County, Texas early Monday morning. It's the 2nd time the 35-year-old quarterback has been arrested for drunk driving.
Young broke his silence on the situation Wednesday night -- saying, "I deeply apologize for letting my family, my friends and my fans down.
"With the help of God and my loved ones, I am going to take aggressive actions to make sure this never happens again. I take full responsibility for my actions."
While he didn't specifically say "rehab" -- seems that (or some kind of alcohol treatment) is the plan here.
