The Mets placed Perez on the 15-day injured list Friday with a left forearm strain.
Perez has tossed 5.2 scoreless frames with a 9:0 K:BB over his last five appearances but will be shelved for at least the next couple weeks. With A.J. Minter having also been dealt, the Mets have added Jonathan Pintaro and Xzavion Curry to their bullpen.
