Kirkland, Wash., Municipal Court Judge Michael Lambo released Stevens at a bail hearing on a charge of fourth-degree assault following a Monday arrest at a home in Kirkland, Seattlepi.com reported.
Police charged Stevens with domestic assault after they were called to the home and observed an intoxicated Solo -- Stevens' reported fiancee -- with blood and a fresh laceration on her elbow.
Solo's brother Marcus had blood on his forehead and knees and a bruised eye, police said in their report. Both allegedly said they had been attacked by uninvited guests during a party.
Authorities, however, said Stevens was found upstairs under a bed with blood on his cheek and shirt.
Lambo cited a lack of evidence and the non-cooperation of witnesses in releasing the former Washington Huskies star, the website reported.
Stevens, 33, is currently a free agent after being released by the Tampa Bay Buccaneers following a 2010 marijuana arrest. He was also arrested last year in connection with a Tampa, Fla., bar fight.
