David Wright is headed to the disabled list with a herniated disk in his neck and is expected to be out for a prolonged period, according to a source.

Wright tried oral anti-inflammatory medication and then received an injection in his neck over the past week, but neither alleviated the symptoms in order for him to return to the field.

Surgery isn't off the table, but Wright will not undergo surgery right now.

"This guy has been a special player in baseball," Terry Collins said. "Certainly being the captain and the face of this organization, a manager's worst nightmare is to see a star start to fade. I think David's got a lot of baseball left in him because of the way he prepares and the way he gets himself ready. But it's hard to watch what he's going through ... as good as he was. I'll tell you: There's a lot of guys in this room that would not do what he does every day just to get ready to go play a baseball game. He's still special. He's still a great player."
