Abbott (shoulder) will not return this season, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Abbott has been throwing and will continue to do so in hopes of going into the offseason without any restrictions, but there's not enough time left in the regular season for him to rejoin the Reds' rotation. The left-hander will finish with a 3.72 ERA and 114:52 K:BB over 138 innings covering 25 starts for Cincinnati this season.
