‘Mighty Ducks’ Star Shaun Weiss Leads ‘Quack’ Chant at Concert

“Mighty Ducks” star Shaun Weissknows how to get a crowd excited … leading an audience in an iconic ‘Ducks’ chant — and tossing out signed gear.

The actor/comedian — best known as Goldberg the Goalie from the ‘Ducks’ trilogy — hit up the House of Blues in Anaheim for country singer Niko Moon‘s tour.

Weiss & Moon are both former addicts, and we’re told Moon wanted to highlight Weiss’ recovery — pointing to him as a “hometown hero” of sorts — since the Anaheim Ducks, who actually got their name from the film series, play real close to the House of Blues.

BTW … Niko’s donating all the streaming proceeds of his new single “Better Days” to the Happy Cowboy Foundation — a charity he founded committed to providing free therapy to those dealing with mental health issues and drug addiction.

Anyhoo, check out the vid … Shaun’s clearly lovin’ the atmosphere handing Niko his own Goldberg jersey — before the chanting began.

If you haven’t seen ‘MD’ … the players hype each other up before a match by quacking together — saying “quack” over and over before a big game. Here, Weiss did the same to hype up the crowd … and damn, did it work.

We’re told Shaun and Niko also jettisoned a few signed jerseys for the fans in the crowd … showing off their baseball skills by chucking the hockey jerseys off the stage.

This all serves as a bit of a celebration for SW too BTW … the former child star recently reached four years of sobriety — though some people didn’t believe it.

Remember, people were recently worried he’d broken his sober streak, but Shaun told us he definitely hasn’t relapsed … and says he’d make sure to ask for help if he backslid.
