UPDATE 6:10 p.m. ET | "Chariot" singer Gavin DeGraw has been discharged from a New York City hospital after being attacked by a group of men in the early hours of Monday (Aug. 8).

DeGraw, 34, suffered a concussion, broken nose, black eyes, cuts and bruises following an altercation with a "group of assailants," his rep confirmed in a statement to Billboard.com on Tuesday. He was taken to Bellevue Hospital by ambulance and was listed in stable condition.

The attack happened five blocks away from the National Underground, a bar and live venue DeGraw owns in partnership with his brother, Joey. He had just left the club for the night and was walking north.

The incident occurred on First Ave. between 5th and 6th Streets in the East Village neighborhood between 3 a.m. and 4 a.m. Monday. A police spokesman tells the Hollywood Reporter that DeGraw claims to have been attacked by three male assailants. He then stumbled off and was hit by a cab 13 blocks away, but was not seriously injured in that collision.

An investigation is underway though no arrests have been made.

"Gavin and his family appreciate everyone's concern at this time," his rep said.

DeGraw spoke to Billboard.com recently about the National Underground. "We want it to be like a neighborhood joint and a little musical joint where local acts can come through and feel comfortable," DeGraw said in a recent interview. "We're just doing what we like. We opened up the little barroom thing in (New York) because we like music."

DeGraw is currently on tour with Maroon 5 and will miss planned concerts Tuesday in Saratoga Springs, NY and two shows this weekend. His fifth album, "Sweeter," hits stores Sept. 20.
