Lincoln Police Capt. Jason Stille says Ian Poulsen was found unconscious in the street around 2 a.m. Sunday after the fight.
Several witnesses told police they say Poulsen fighting with two other men before Poulsen fell to the ground and hit his head on the concrete.
Police arrested a 22-year-old man and a 25-year-old man a few blocks away. They are suspected of first-degree assault.
Poulsen remained in serious condition at a local hospital Sunday morning, but police aren’t sure if he will survive his injuries.
