Curt Schilling has an undisclosed right shoulder injury and has been squabbling with the Red Sox over the need for surgery that could keep him out for all of 2008, the Boston Herald reported.
For now, though, the starting pitcher, who previously said 2008 will be his final season, will rest.
"There have been disagreements these past few weeks in an effort to provide me with a solution that would allow me to pitch as much as possible during the 2008 season," Schilling wrote on his blog. "At no time did I ever consider taking a course of action against the club's wishes."
The Herald reported Schilling, 41, could be out until the All-Star break even without surgery. Neither he nor the team commented on when he will pitch again.
The dispute prompted him to consult with the union. According to the collective bargaining agreement, a player can seek a second opinion from his doctor, but it's in dispute what happens when that differs from the opinion of the team doctor.
Said Michael Weiner, a union lawyer: "The Red Sox have no basis to take any action against Curt."
Schilling spent seven weeks on the disabled list with right shoulder tendinitis last season.
