Koji Uehara's return to Boston's bullpen is imminent, according to Sean McAdam of Comcast SportsNet, who notes the 39-year-old will throw a bullpen session on Wednesday.

Shoulder soreness has sidelined Uehara for the last four games, though an MRI revealed no structural damage to his right arm. Uehara has yet to allow a run over five appearances this season, notching seven strikeouts while issuing no walks over five innings of work.
