Jenrry Mejia has been placed on the DL. Terry Collins presumed Mejia would undergo surgery soon to remove the bone spur and miss the remainder of the season.
Sidearm reliever Greg Burke has been promoted from Triple-A Las Vegas for bullpen duty.
Collins added that the two "immediate" options are to have Carlos Torres fill in for a start or skip Mejia's turn because Thursday is a team off-day. In the latter scenario, however, Matt Harvey and Zack Wheeler would have to pitch on standard rest, further jeopardizing their ability to complete the season before hitting innings caps.
If Torres were to start, Collins said, it would not be to complete the season. Instead, young pitchers in the minors not facing innings limits would be used.
