Original story:

A brawl at a party early Saturday morning in Pullman, Washington, left two Washington State students in the hospital and six Cougars football players as persons of interest in the police investigation.

According to The Spokesman-Review, Pullman police have confirmed that football players were present at the party and are persons of interest in what police commander Chris Tennant said would be a "lengthy investigation."

"We're looking at this as a very serious felony assault level based on the injuries to two victims," Tennant said. "I would like to make arrests later in the week. I don't know if that's a realistic timeline. I expect this to be a lengthy investigation. A lot of people have to be interviewed."

The fight reportedly began after firecrackers or fireworks were thrown at a student party, leading to a verbal altercation that turned physical.

The six football players have not been named and the school's associate AD Bill Stevens told The Spokesman they are aware of the situation and that it's a "team matter."
