Gallagher (oblique) was officially activated from the injured list Sunday. He isn't included in the lineup for the Royals' series finale with the Orioles.
Gallagher had been sidelined since Aug. 7 with an oblique injury and is likely set to split time behind the dish with Meibrys Viloria and Nick Dini to close the campaign. For the season, Gallagher is hitting .238/.312/.365 in 45 games.
