Falter is expected to start Friday's game against the Pirates, Jim Salisbury of NBC Sports Philadelphia reports.
Falter started the second game of Saturday's doubleheader against the Mets and allowed a run on two hits and two walks while striking out three in six innings to earn the win. Although he was sent back to the minors, he'll rejoin the Phillies to start on normal rest Friday after Zack Wheeler (forearm) was placed on the 15-day injured list Thursday.
