Protestors Try Storming Barclays Center Over Kyrie Vaccine Issue

Kyrie Irving has some in his corner who are willing to go to war for him over his vaccine stance -- and we mean that literally ... 'cause they were doing just that this weekend.

A group of protestors hit the streets Sunday to advocate for the Brooklyn Nets star, who's sidelined right now since he's not vaccinated ... which is preventing him playing with the team whatsoever, due to NYC's vaccine mandate and the team's wider policy.

Well, these folks think it's BS -- and apparently were itching to get inside to let Nets officials know first-hand, 'cause they were attempting to storm the Barclays Center's front entrance ... shortly before tipoff against the Hornets.

Check out this footage ... demonstrators clashed with security, and bowled over barricades.

It sounds like the chaos only lasted for a short time, and eventually ... cops and security got it under control. So, it appears to have been a flash mob type deal. Still though ... pretty damn intense for however long they were there. Things escalated quickly, as you can see.

Meanwhile, it doesn't seem Kyrie is caving to the pressure -- he's been mostly laying low since making his POV clear ... namely, that he's against mandates, not vaccines.
