Maybe Daniels who, along with the rest of the Packers defense, spent nine of the final 15 minutes of the game on the field due to the Packers inept, turnover prone offense, could not find time for a bathroom break.
Or, it could be something much more innocent: sweat.
Daniels himself tried to set the record straight after the game, telling ESPN Wisconsin's Jason Wilde that he did not soil himself:
Daniels was very serious talking about #Packers loss but joked about this photo. “I saw that. I sweat a lot down there. Everybody was like, ‘Did you pee your pants?’ No, I did not pee my pants.” https://t.co/s6wJsDV3Vd
