Warning: Glee Spoiler!

DIANNA AGRON'S character on "Glee", Quinn, was in a BAD car accident on last night's episode.  She was TEXTING AND DRIVING when a truck slammed into her . . . and that's how the episode ended.

The good news is:  Quinn did NOT die . . . and she'll be back when "Glee" returns from its two-month hiatus.  The next new episode is scheduled for April 10th.

But she's coming back in a WHEELCHAIR.

Pictures from the "Glee" set have surfaced online . . . and they show Quinn in a wheelchair and a helmet.  It looks like she's preparing to race KEVIN MCHALE'S character Artie, who's been in a wheelchair since the show began.  

There's no word how long Quinn will be in a wheelchair.
