Braun is still expected to be ready for Opening Day.
Brewers manager Craig Counsell had said the team was targeting the second week of spring games for Braun. However, he told the Brewers' television crew during an in-game interview Monday that although the slugger is responding well to his activities, he won't play that soon.
Braun is switching back to left field this year after a stint in right. He hit .285 in 2015, with 25 home runs and 84 RBIs. He had the surgery to relieve a bulging disk in his lower back.
