Rey Maualuga is in trouble with the law again ... the former NFL and college football star was arrested on Wednesday, TMZ Sports has learned.
Jail records show the 34-year-old -- who was a 2nd-round pick in the 2009 NFL Draft -- was booked into Kenton County Jail in Kentucky at 8:19 PM.

Maualuga -- who was listed at 6-foot-2, 245 pounds on his booking sheet -- was arrested by the Villa Hills Police Dept.
