Jalen Carter's March didn't get any better on Wednesday ... the top NFL draft prospect struggled in front of scouts at his Pro Day at the Univ. of Georgia.
Just two weeks after he was hit with criminal charges stemming from his alleged role in a fatal January car crash, Carter took the field at UGA in an attempt to prove he still belonged as a top-five pick ... and by all accounts, he had a rough day.
Reporters on the scene said he showed up at 323 pounds -- nine lbs heavier than what he weighed at the NFL's scouting combine some 14-or-so days ago.
