Lockridge (knee) was sent to Triple-A Nashville on Thursday to begin a rehab assignment.
Nashville's game Thursday was postponed by inclement weather, so Lockridge's first rehab game was pushed back a day. The outfielder is recovering from arthroscopic surgery to address cartilage damage in his right knee. Lockridge has not played in a game since early May, so he will likely require more than just a few rehab contests. He's also facing an uncertain playing time situation upon activation, as the Brewers' outfield situation is crowded.
