Anthony Pettis squabbles with UFC champ Rafael dos Anjos via cereal boxes

Anthony Pettis and Rafael dos Anjos

Who knew cereal boxes could be such a sore subject for two of the lightweight division’s biggest stars?

Reigning UFC 155-pound champion Rafael dos Anjos dethroned ex-titleholder Anthony Pettis with a big upset in March, and the two vets didn’t exactly find common ground after the bout.

Their rivalry popped up again overnight when dos Anjos took aim at Pettis, who became the first fighter on a Wheaties box. But with Pettis no longer holding the belt that adorns those cereal boxes, dos Anjos warned about “expired” versions (via Twitter):

Hey kids, whatch out for expired boxes ??????||—>>>Aí criançada, cuidado com as caixas vencidas #RDA #AndStill #ufc

Pettis, though, fired back with a cereal box of his own (via Twitter):

Despite the obvious marketability of a rematch, dos Anjos and Pettis have other upcoming challenges.

Dos Anjos (24-7 MMA, 13-5 UFC), who’s ranked No. 1 in the NOS Energy Drink MMA lightweight rankings, looks for his first title defense when he meets No. 4-ranked Donald Cerrone (28-6 MMA, 15-3 UFC) in UFC on FOX 17’s headliner on Dec. 19. No. 3-ranked Pettis (18-3 MMA, 5-2 UFC), meanwhile, is expected to fight No. 6-ranked Eddie Alvarez (26-4 MMA, 1-1 UFC) at UFC Fight Night 81 on Jan. 17.
