Shaun Weiss -- who played Goldberg in 'The Mighty Ducks' -- got busted again 5 days after serving a jail sentence ... this time for meth.
Law enforcement sources tell TMZ ... cops in Burbank got a 911 call last Wednesday for a suspicious person stumbling around yards in a neighborhood near the Warner Bros. studio lot.
Cops responded and arrested Weiss around 2:30 PM, booking him for possession of a controlled substance. We're told he had meth on him ... unclear exactly how much, though. He's being held on a $20,000 bond.
