Tristan Lambright admitted the violation in Orchard Park Town Court on Thursday. He'll have to do 25 hours of community service and pay $400 in fines and fees.
The 29-year-old ran out onto New Era Field on Nov. 12 during the Bills' 47-10 loss to the New Orleans Saints. He was tackled by security officers.
After his arrest, fans rallied around him, offering praise for his physique and money for his defense. But he won't be at another game anytime soon. His sentence includes a one-year ban from the stadium.
