Aaron Hernadez's brother, D.J. Hernandez, could get hauled to jail in Connecticut once again ... TMZ Sports has learned a re-arrest has been ordered for him after he failed to show up last week for a hearing in his ESPN brick-throwing case.
According to court records, D.J. was supposed to be at a courthouse in New Britain for proceedings on Friday ... though an official tells us he didn't appear.
During the alleged incident in Bristol ... cops say D.J. -- Aaron's older brother and a former Division 1 football player -- attached a note to the object which read, in part, "It's about time you all realeyes the affect media has on all family members."
"Since you're a world wide leader maybe you could lead how media and messages are delivered brick by brick. Clean it up!"
D.J. was also hit with criminal charges in a separate incident that authorities said happened just days prior to the one in Bristol. In that case, D.J. was arrested after being accused of leading cops on a wild car chase after they attempted to pull him over for a routine traffic stop.
D.J., though, reached a deal with officials in April to close out that case ... pleading guilty to one count of failure to drive in a proper lane and one count of failure to use traffic control signals. In exchange, prosecutors dropped the other charges against him -- which included reckless driving and engaging police in pursuit.
He was ordered to pay $100 in fines ... and that matter was closed.
