L.A. Dodgers hero Cody Bellinger confirmed what we were all thinking ... he DID dislocate she shoulder while celebrating his game-winning HR on Sunday.
... but he popped it right back in and now he says he's good to go!
25-year-old Bellinger smashed a solo donger in the 7th inning of the NLCS -- giving the Dodgers a 4-3 lead, which ultimately was enough for L.A. to beat the Houston Astros.
After he crossed home plate, Bellinger shared a jumping forearm bash with teammate Kike' Hernandez -- and viewers could see, it appeared Bellinger suffered an injury during the celebration.
