Dallas Cowboys linebacker Rolando McClain was convicted of resisting arrest and disorderly conduct in Alabama this morning over an incident where he cussed out cops back in 2013 ... and was sentenced to 18 days in jail.
McClain -- a 1st round pick in 2010 NFL Draft -- was arrested at a park in Decatur last year when cops arrived to the scene to break up a large crowd and McClain began to cuss and scream at one of the officers.
McClain appeared in court this morning -- where prosecutors used dash cam video to prove McClain was out of control.
But as soon as the judge sentenced Rolando to 18 days in the slammer -- the NFL player appealed to state court ... and then left to catch a plane back to the Cowboys practice facility in California.
