Major League Baseball’s long-running performance-enhancing drug saga took another turn this week, with ESPN.com reporting that the league is poised to suspend dozens of players—including such stars as Milwaukee Brewers outfielder Ryan Braun and New York Yankees third basemen Alex Rodriguez—over their ties to the defunct Miami anti-aging clinic known as Biogenesis.

An MLB spokesman told The Am Law Daily on Wednesday that the league is in the midst of an ongoing investigation related to Biogenesis and declined further comment. And while other media outlets have subsequently reported that league officials have not yet made a final decision on whether suspensions will be handed down, the union representing MLB players is taking the issue seriously enough that it has hired its own outside counsel in connection with the matter.
