Braun, who leads the Brewers with three Spring Training home runs and is tied for second on the team with nine RBIs entering Sunday's game, was first scratched from the lineup on Wednesday because of the problem. He didn't play Thursday as a precaution, did appear Friday night against the Padres, then was held out again on Saturday.
"We don't know what's bringing it on," manager Ned Yost said. "It might be a new pair of shoes that he put on. It might be an exercise program that he was doing. He's got stiffness in his Achilles and there's no sense taking chances. ... I don't see it to be anything major."
Braun will not play in split-squad games Monday, Yost said. Beginning Tuesday, Braun will be evaluated each day.
"Whenever it feels better," Yost said when asked Braun would play again. "The common sense thing is to let it [subside]. It could be a pair of shoes. We think it's a pair of shoes that he's been wearing."
On Sunday, Joe Dillon replaced Braun in left field for a game that was televised back in Wisconsin.
Braun has played in 12 games this spring as he works on the transition from third base to left field. He won last year's National League Rookie of the Year Award after batting .324 with 34 home runs and 97 RBIs.
