And Samuel L Jackson posted: "#waitwaitwait, Ryan Coogler & Michael B Jordan, Thanks for acting with me!!! Loved Sly but...(sic)"
However, Coogler didn't seem to upset by the snub.
He said backstage: "No, no, no! Not at all. I don't know what's happening on Twitter but I love Sly ... And what he said was so nice! (sic)"
Creed saw Stallone reprise his role as boxer Rocky Balboa for the spin-off movie and he praised the character as the "best friend" he ever had.
He said in his speech: "I wanna thank Rocky, the best friend I ever had ... I am the sum total of everyone I've ever met."
The veteran actor also paid a touching tribute to his wife Jennifer Flavin.
He said: "Having your love is the greatest award in the world every day."
Stallone - who previously won a Golden Globe in 1977 for the first Rocky movie - had earlier walked the red carpet at the Beverly Hilton Hotel with his wife and daughters Sophia, 19, Sistine, 17, and 13-year-old Scarlet.
