UFC heavyweight interim champion Fabricio Werdum put Jon Jones on notice last night after Jones defeated Daniel Cormier via unanimous decision.
Werdum took to Twitter to warn Jones against a potential move to heavyweight.
@JonnyBones good fight tonight against @dc_mma but better you stay there at your division. #vaicavalo @danawhite
