CHICAGO (WBBM/AP)- A labor relations law expert predicts some very sticky moments in the years to come as Major League Baseball and its players union try to sort out the issue over the use of performance-enhancing substances. 

WBBM's Bernie Tafoya reports.

University of Illinois College of Law Professor Michael LeRoy thinks there’ll be an attempt to re-open the major league baseball collective bargaining agreement before it expires in 2011 and that there could be a tit-for-tat that includes Major League Baseball giving amnesty to anyone named in the Mitchell Report in exchange for a very rigorous, transparent testing program.

"Even though the parties have had a terrible time reaching agreement about it, now that the damage is much more clearly done, the union will be under more pressured to come to more sensible and comprehensive agreement."

Professor LeRoy also thinks some players named in the Mitchell Report might file a union grievance because they’re named as steroid users without solid proof.

On Wednesday, former Senate Majority Leader George Mitchell's much-anticipated report on performance-enhancing drugs in baseball was released.

In all, the 409-page report identified 85 names to differing degrees, putting question marks if not asterisks in the record book and threatening the integrity of the game itself.
