The report states that Braun refused to answer questions when meeting with MLB investigators last month about his involvement with Biogenesis, a Miami-based clinic which has allegedly supplied players with performance-enhancing drugs.
Accoring to the report, Braun, Alex Rodriguez, and as many as 20 other players are expected to be suspended as soon as after next week's all-star break.
MLB could pursue as much as a 100-game suspension for Braun, claiming multiple violations of the league's PED policy.
The Milwaukee Journal-Sentinel quoted an MLB spokesperson who called the ESPN report "premature" and that no decision has been made as of yet.
Braun refused comment to reporters via a team spokesperson on Tuesday evening. The Brewers left-fielder is returning to the starting lineup for the first time in a month as Milwaukee takes on the Cincinnati Reds Tuesday night at Miller Park.
