Zuckerman Spaeder has brought on Jon Fetterolf, a white-collar, civil litigation and sports lawyer. Previously, he was a partner at Williams & Connolly for six years.

Fetterolf has represented companies and individuals under investigation for price-fixing, bribery and a host of other types of fraud and conducted investigations relating to the Foreign Corrupt Practices Act, Zuckerman Spaeder said in a press release.

He also represents coaches, athletes, their families and agents through his sports law practice. Fetterolf works with sports agencies and players in fee disputes, including pitcher Ross Ohlendorf in a 2011 salary arbitration hearing against the Pittsburgh Pirates. A three-judge panel awarded Ohlendorf a $439,000 raise despite a 1-11 record in the 2010 season, according to The Associated Press.

“[Fetterolf’s] expertise in FCPA litigation and government and internal investigations fits perfectly with our firm’s national reputation in white collar criminal defense matters,” Zuckerman Spaeder chairman Graeme Bush said. “His arrival also allows us to launch a more robust sports law offering, which complements our existing experience representing sports figures in litigation and investigations.”

Although Fetterolf is the firm’s first certified sports agent, working with the Major League Baseball Players Association, Zuckerman Spaeder lawyers have tackled sports litigation before. Partner Cy Smith represented the family of the late Pittsburgh Steeler Mike Webster in the first win against the National Football League pension plans. And the firm represents former professional football players and their spouses who have sued the NFL over head injuries.

Fetterolf is the fifth partner to leave Williams & Connolly since 2012, judging by the number of partners’ biographies removed from the firm website.

Another Williams & Connolly partner, James Tanner, departed from the Washington-based litigation firm in October to open his own sports and entertainment management firm, Tandem Sports + Entertainment, in Arlington, Va. At the time, Tanner said changes at the National Basketball Association, including a new commissioner, prompted him to start his own business. He represents, among others, NBA standout Jeremy Lin.

Fetterolf was not available for comment Wednesday. Robert Barnett, a member of Williams & Connolly’s executive committee who has represented sports and media stars, declined to comment on possible changes within the firm’s sports law practice.

Fetterolf graduated from the University of Michigan Law School and had clerked in the U.S. Court of Appeals for the Ninth Circuit and in the U.S. District Court for the Eastern District of Pennsylvania. He started work at Zuckerman Spaeder on March 13.

Zuckerman Spaeder is a litigation boutique with about 100 lawyers and offices in New York, Tampa, Baltimore and Washington.
