Longoria is not in the lineup Monday against the Marlins because his left foot is bothering him, Marc Topkin of the Tampa Bay Times reports.
The specifics of the injury aren't yet known, though it doesn't appear to be overly serious, as Longoria said he's still hoping to play Tuesday. Longoria said the ailment is similar to the plantar fasciitis in his right foot that hobbled him during the 2013 season, so the Rays may want to take a cautious approach with the 31-year-old. He should be considered day-to-day until the Rays release more on his status.
