The New York Mets are one game behind the Nationals for first place in the NL East, but it appears the Mets could be without one of their leaders for some time.

Veteran third baseman David Wright received a neck injection Tuesday, but manager Terry Collins is very apprehensive about the Wright's status.

"Obviously, a herniated disk can be a serious thing," Collins told ESPN. "The doctors feel this is the next step."

Collins said the injection could take 48 to take effect. The Mets opted to keep Wright, who is batting .227 with seven homers and 14 RBI this season, on the active roster. If Wright doesn't respond well to the medication, he might be headed to the disabled list.

Wright played in only 38 games last season as he rehabbed a back injury that flared up while he was coming back from a hamstring injury.
