Michael Sam is getting support from one of the biggest pop stars in the world -- Harry Styles ... who rocked the football player's jersey during a One Direction concert in St. Louis yesterday.
Harry threw on a #96 St. Louis Rams jersey with Sam's name across the back during the a performance at Edward Jones Dome ... where the Rams play.
It's an interesting move for Styles -- whose bandmate Liam Payne came under fire for his support for the "Duck Dynasty" guys after the reality stars came out against gay marriage.
Sam has had a helluva week -- not only with teammates rallying behind him after ESPN ran a story about his locker room showering habits ... but he also survived the 1st round of cuts.
