Hernandez did not have the tattoo when he last appeared in court last month, on the day a jury found him guilty of murdering Odin Lloyd and he was sentenced to life in prison without parole.
Hernandez was reportedly involved in a fight on Monday that was believed to be gang-related. After the fight, ABC News reported, prison officials found Hernandez had a new tattoo that referenced the Bloods gang. The report didn't say where that tattoo was.
Hernandez was in court to plead not guilty to a charge of witness intimidation for allegedly shooting a friend in the face. The man is expected to be a key witness in Hernandez's upcoming double murder trial for the 2012 killing of Daniel de Abreu and Safiro Furtado.
