Palacios is out of the lineup for Wednesday's game against the Blue Jays, Marc Topkin of the Tampa Bay Times reports.
Palacios seemed to have taken hold of a strong-side platoon role upon his return from the 60-day injured list Sept. 1, but he's now been out of the lineup for three straight matchups versus right-handed pitchers. The Rays will go with Bob Seymour at first base for the second day in a row.
