Ruben Tejada and Ramon Ramirez will both be activiated, the Mets tweeted from their official account.
Jordany Valdespin has been demoted to Triple-A Buffalo. The Mets have put Frank Francisco on the 15 day DL.
Tejada has been on the disabled list since early May with an injured right quadriceps. Ramirez was on the DL with a strained right hamstring. The right-hander suffered the injury celebrating Johan Santana's no-hitter.
Tejada will start at shorstop on Sunday night against the Yankees and bat second.
Ike Davis, who missed Saturday's game due to a bout with food poisoning, remains out of the lineup.
