Singer Gavin DeGraw remained hospitalized on Tuesday (August 9) after being beaten by a group of unknown men in New York's East Village early Monday morning. DeGraw suffered a concussion, a broken nose and other injuries, his rep told MTV News.

Police continue to investigate the incident. A DeGraw spokesperson released a statement on Monday revealing that the singer was taken to Bellevue Hospital in an ambulance and is still being held for observation. The assault forced the "I Don't Want to Be" singer to cancel a Tuesday show in Saratoga Springs, New York, where he was slated to open for Maroon 5 and Train. He is also scheduled to appear on "Live! With Regis and Kelly" on Wednesday and participate in a LiveStream performance session for fans that same day. It is unknown whether he will be able to make those appearances.

The New York Post reported that New York native DeGraw, 34, had been out drinking with a group of friends late Sunday night before splitting off by himself. The attack occurred after 3:50 a.m. and police do not believe it was a robbery attempt. A New York Police Department press officer told MTV News that there was no update on the case as of Tuesday morning and that no arrests had been made. The spokesperson also confirmed reports that after the beating, DeGraw continued walking and was struck by a taxi, though he was not seriously injured in that incident.

A spokesperson for the singer confirmed to MTV News on Tuesday that he had been hospitalized and was being treated for his injuries. "Gavin DeGraw is currently recovering and in stable condition at Bellevue Hospital where he was taken late Sunday night by ambulance after he was attacked by a group of assailants. He suffers from a concussion, broken nose, black eyes, cuts and bruises. The police are conducting an investigation of the attack.

"Gavin and his family appreciate everyone's concern at this time," the statement continued. "We have no information yet regarding his upcoming concert dates and promotion for his new album."

The singer is preparing to release his fifth album, Sweeter, on September 20. According to
