Jackson was recalled from Triple-A Oklahoma City on Thursday, Juan Toribio of MLB.com reports.
EDGE Analysis
Jackson has posted a 1.04 ERA and 1.38 WHIP in 8.2 innings across a pair of relief appearances in the majors this year, and he'll rejoin the Dodgers' bullpen ahead of Thursday's series finale in St. Louis. The right-hander allowed five runs (four earned) in 4.2 innings in his most recent minor-league appearance but will attempt to replicate his past success in the big leagues.
