The Rams weren't the only ones getting rings on Sunday ... 'cause safety Taylor Rapp proposed to his GF, Dani Johnson, right after L.A.'s huge win!!
The moment happened right on the field ... with the 24-year-old getting down one on knee and asking "Will you marry me?" before presenting Johnson with an engagement ring.
It was incredibly special ... and a few Rams players and supporters of the couple cheered the entire time as the proposal happened.
Johnson -- who was overwhelmed with emotion -- shook her head in acceptance .
