Knicks rookie forward Danilo Gallinari could undergo season-ending surgery on his back, the team announced on Tuesday.

"Because Danilo has said his back is only 60 to 70 percent, we want to reconsider all treatment options, including surgery. Yesterday he saw a fourth surgeon in New York. Danilo has decided to travel to Italy to get additional opinions from Italian back specialists. He's leaving today and will return Monday at the latest," the club released in a statement.

Gallinari has been playing in pain and could have a degenerative condition of more than one bulging disc in his back.
