Aaron Donald ain't just a monster on the field ... he's a hero off of it too -- 'cause Make-A-Wish recipient Kyle Frazier tells TMZ Sports the Rams star helped him beat cancer, and then gave him some great football advice as well!!
The 21-year-old college football player -- who beat Hodgkin's lymphoma in 2019 -- initially met Donald over Zoom in 2020 as part of his Make-A-Wish request.
At the time, due to the pandemic, the duo could only talk remotely ... although Frazier said it helped him recover from the disease, and ultimately assisted him on his way to playing as an offensive lineman at Savannah State University.
