Kirk Nieuwenhuis has been sidelined with a pinched nerve in his upper back for the last three games.
The Mets were contemplating putting him on the disabled list on Saturday, but left him active while demoting Michael Conforto to make room for Yoenis Cespedes on the active roster.
But on Sunday, the Mets decided to place Nieuwenhuis on the disabled list anyway, and recalled Conforto from Triple-A Las Vegas.
Because Conforto is an injury replacement, he does not need to wait ten days before being recalled from the minor leagues.
Nieuwenhuis is 13-for-41 with three home runs and ten RBI in 17 games since having his contract purchased from Triple-A Las Vegas on July 6.
