Gavin DeGraw was assaulted early Monday morning and hospitalized for injuries, including a concussion and broken nose, a rep for the musician said.

The singer, perhaps best known for his Platinum album “Chariot,” was attacked by a group of three men in the East Village, a New York City police spokesman said. It is not clear what the men look like or what the motive for the attack was. DeGraw then walked 13 blocks from scene and was struck by a cab, police said: “A witness who saw him being struck by the cab called.”

The 34-year-old suffered a concussion, broken nose, facial cuts and black eyes from the assault, his publicist said. He was taken to Bellevue Hospital by ambulance where he remains hospitalized in stable condition.

DeGraw was set to perform with bands Maroon 5 and Train in Saratoga Springs, N.Y. on Tuesday. The groups have been touring together this summer.

Adam Levine, lead singer of Maroon 5 and a “The Voice” judge, tweeted his support: “Please send your love to @gavindegrawtonight. We love you buddy. Get well and get back out here!”
