Maeda will make his next start on Sept. 20 or Sept. 21 against the Phillies, Ken Gurnick of MLB.com reports.
Maeda was originally scheduled to take the mound this Sunday against the Nationals, but manager Dave Roberts has decided to replace him with Hyun-Jin Ryu for that contest and shift Maeda back a few days to face off against the Phillies, who represent a much more enticing matchup.
