Phil Mickelson has been named as a "relief defendant" in a federal lawsuit accusing two other individuals of insider trading.
The Securities & Exchange Commission filed charges Thursday against Thomas Davis, the former chairman of Dean Foods, and noted sports gambler Billy Walters, accusing both of "repeated and very profitable insider trading" tied to the Dean Foods stock.
According to a Reuters report, as a relief defendant Mickelson is not accused of any wrongdoing, but "has received ill-gotten gains as a result of others' illegal acts."
According to the lawsuit, Mickelson had placed bets with Walters both before and after July 2012, when Walters called Mickelson and conveyed "material nonpublic information" regarding Dean Foods stock, which he encouraged Mickelson to purchase.
