Chicago Bears Stud -- Convicted In Parent/Teacher DUI Case

Chicago Bears defensive back Tim Jennings -- who was busted for DUI on his way to a parent/teacher conference -- will NOT be going to jail ... after striking a plea deal with prosecutors.

Jennings -- a 2-time Pro Bowler and a huge part of the Chicago defense -- was arrested back in January after cops say he was going nearly 100 mph on a Georgia interstate.

Cops say his breath reeked of booze -- but Jennings said he had stopped drinking 10 hours before and was speeding because he was late to his kid's parent/teacher conference at school.

Now, we've learned Jennings cut a deal -- pleading guilty to reckless driving. As for the DUI charge, that was tossed.

Jennings was sentenced to 12 months probation and must complete 40 hours of community service -- and it CAN NOT be football related.

He's also required to complete a DUI program and pay a fine.

12:24 PM PT -- Jennings' attorney issued a statement to TMZ Sports saying the DUI charge was "completely dismissed today due to a lack of evidence to proceed on the DUI."

"From the inception of this case, Mr. Jennings admitted that he was speeding when encountered by law enforcement. Mr. Jennings steadfastly denied that he was driving while under the influence."
