"I saw somebody start fighting, and I broke it up," the rookie wide receiver said after the team's 34-31 win. "That's all it was to me."
Someone on Twitter then asked Doss why he was getting involved in a fight on the day of a game. The player responded that he didn't care "wat day it is I'm not gonna sit there and let someone get jumped. [I don't know] where ur from but we don't do that in Indy."
Five Guys manager Carl Fisher said police told his employees that a Ravens player had intervened in the fight.
"I mean, it was two dudes on one,"" Doss said. "I was trying to help the situation out. I broke it up. ... I saw the guy on the ground bleeding, and I saw a guy on top hitting him. So I stopped it."
Baltimore police spokesman Anthony Guglielmi could not confirm that Doss had broken up the fight but said a dispute erupted in the Pratt Street Pavilion restaurant about 4:30 p.m. He said two men, one believed to have been angry about getting fired, cut the 34-year-old manager with a knife.
Guglielmi said the two men, both former employees, ran from the restaurant but left the knife behind. The manager suffered a minor cut on his chin and was treated at an area hospital and released, the spokesman said.
Police said the attackers were being sought.
Earlier Thursday afternoon, Doss had posted on Twitter that he was visiting the National Aquarium in Baltimore, but left, saying: "It's too crowded in here."
