NFL's Antonio Brown: Screens 'Concussion' For HS Football Team

Pittsburgh Steelers superstar Antonio Brown had an early Xmas gift for a local high school football team -- taking the entire squad to a screening of "Concussion" ... TMZ Sports has learned.

Brown hooked up the kids at Clairton High School in Pennsylvania -- a team he's essentially adopted since joining the Steelers.

Clairton head coach Wayne Wade tells us ... Brown organized a bus to take the players to a nearby theater and treated the kids to a night at the movies.

Wayne says Brown is always doing cool stuff for the high school -- "A couple years ago he paid for the whole team to go to Dave N Busters after the season."

So, why Clairton??

"He loves the whole small town, small team, small program thing. We are the winningest program in Pennsylvania, piled up 66 wins in a row (Pennsylvania record), won state championships."

Plus, Wayne played Arena League football with Antonio's dad.

So, what did we learn today ... people actually ARE going to see movies other than 'Star Wars.'
