Reynolds is not in the lineup Tuesday against the Cubs, Kevin Gorman of TribLive.com reports.
Reynolds went 1-for-2 with two walks in Monday's series opener versus Chicago, but Andrew Fillipponi of 937 The Fan in Pittsburgh hears that the 28-year-old outfielder is headed to the 15-day injured list with an oblique issue. There should be an official update soon from the Pirates.
