The fracture was discovered during a scan two days ago and confirmed by further tests.
Wright, 28, will have no baseball activity for 10 days before being re-evaluated at the Manhattan-based Hospital for Special Surgery, the Mets said yesterday in a news release.
The five-time Major League Baseball All-Star was injured April 19 when he dove to make a tag at third base, Mets General Manager Sandy Alderson said. Wright has a .226 batting average this season, with six home runs, 18 runs batted in and nine stolen bases.
The Mets will replace Wright on the roster with infielder Nick Evans from their Triple-A minor-league affiliate in Buffalo.
