Erin Andrews -- Back On with Jarret Stoll ... After Coke Bust

Seems NHL star Jarret Stoll dodged TWO bullets after his cocaine arrest in Vegas -- 'cause not only did he duck jail, but now it seems he managed to hang on to his celeb GF too!

For the first time since he was busted allegedly trying to smuggle coke into a Vegas pool party, Stoll was out in public with his longtime girlfriend Erin Andrews.

There were rumblings Andrews dumped his ass after the Vegas drama ... but the two hit up a NASCAR event at the Sonoma Raceway this weekend ... acting as couply as they used to be.

As we previously reported, Stoll was facing 4 years behind bars ... but struck a plea deal in which he basically has to do some community service.

Dude's gettin' second chances all around -- don't blow it.
