More trouble for Aldon Smith … the ex-NFL star was arrested (again) for allegedly driving under the influence.
Smith — a former All-Pro linebacker — was arrested early Tuesday morning on suspicion of DUI in Mission, Kansas … after cops say he was speeding and illegally changing lanes.
Officials say they suspected Smith was drunk … so they put him through sobriety testing — which he bombed.
Police placed him under arrest and hauled him off to Mission Police Department … where he was processed.
Cops say they tried to administer a breathalyzer … but Smith refused.
Officials then issued citations to Aldon … and after he posted bond, he was released to a friend.
This ain’t the 1st alcohol-related incident involving Smith … he’s been popped for at least 2 other DUI’s in the past.
His drinking got so bad … Aldon checked himself into alcohol rehab last March — and his former fiancee told us she feared for his life.
Smith — a former 1st-round pick — hasn’t played a down of professional football since 2015.
