O'Neill is not in the lineup for Friday's game against the Rays, Chris Cotillo of MassLive.com reports.

O'Neill has been in and out of the lineup lately, making just two starts over the last six contests. He missed the first two of those tilts with a back injury, although it's not clear whether the back is a factor in his two other absences. Jarren Duran is in left field for the Red Sox on Friday.
