2019 Polaris 900xp Ranger

New to the group and need some help. Trying to figure out a problem I discovered while changing the oil on my Ranger this past weekend. I notice about a 1/2 of metal on drain plug when I pulled it out. I drained the oil out of the pan and notice a copper looking ring, about the size of a qtr. it was split in two. Oil had a metal flake to it as well. Machine runs fine, didn’t burn any oil either.
