Siri was unavailable for Sunday's loss to the Yankees due to kidney stones, Marc Topkin of the Tampa Bay Times reports.
The 27-year-old started the first 20 games of the season, and the kidney stones help explain his absence from the lineup for two of the past three games. Siri will fly back to Tampa Bay with the team and should be considered day-to-day heading into Monday's series opener versus the White Sox.
