Josh Rosen Says Opposing Players Hurled Anti-Semitic Insults

Josh Rosen says he's been the target of A LOT of anti-Jewish trash talk on the field -- with some opposing players telling him, "Stay the f*ck down, you Jewish bastard."

The former UCLA quarterback opened up about the anti-Semitism in football to NFL.com's Michael Silver ... saying when it comes to trash talk, "I get a lot of Jewish things."

"My nose, particularly. I get, like, 'Stay the f*ck down, you Jewish bastard … I'm gonna break your f*cking nose, you Jew.'"

Rosen says he's unfazed by the insults -- explaining, "I really like when people try to get in my head."

"I like away games more than home games. I like silencing crowds; that's a big thing. One of my best games was at Arizona my freshman year. It was College GameDay and they had a ton of banners; they had my face on the queen from 'Frozen'. They had, 'Josh Rosen's Bar Mitzvah Wasn't Even Lit.'"
