Palacios is out of the lineup for Sunday's game against the Orioles, Marc Topkin of the Tampa Bay Times reports.
Palacios will hit the bench along with fellow left-handed hitters Jonathan Aranda, Ben Rortvedt and Brandon Lowe as the Rays roll with a full right-handed-hitting lineup versus Orioles southpaw Cole Irvin. Jonny DeLuca will replace Palacios in right field and will bat seventh.
