Attorneys for Bryan Stow and Frank McCourt reached an agreement Wednesday that averts the possibility that the San Francisco Giants fan beaten outside Dodger Stadium three years ago might have had to pay up to $400,000 in trial costs to the former Dodgers owner.After a session in chambers with Los Angeles Superior Court Judge Victor Chavez, the lawyers emerged and said Stow is dropping his request for a short trial on one unresolved legal issue in exchange for McCourt agreeing not to seek recovery of his expenses.
