Jones is a former U.S. Attorney for Minnesota.
According to a source quoted by ESPN, NFL Commissioner Roger Goodell is creating the position for Jones. A second position, special counsel for investigations, will be filled by Lisa Friel, a former New York District Attorney's office sex crimes prosecutor.
Jones will be the league's chief disciplinary officer, administering the personal conduct policy that applies to players and all other NFL employees, according to the Minneapolis-St. Paul Business Journal.
Goodell himself has been carrying out those duties in recent years and has come under fire for his handling of several high-profile cases, including that of Vikings running back Adrian Peterson.
Goodell suspended Peterson after charges were filed claiming Peterson had disciplined his 4-year-old son with a wooden switch. Peterson recently won an appeal of his suspension.
ESPN says Friel will professionalize the investigation process.
Jones twice held the position of U. S. Attorney for the District of Minnesota. President Clinton first appointed him in 1998, and he served until January 2001, when he returned to private law practice. Jones was appointed again in 2009.
He earned his B.A. from Macalester College and his law degree from the University of Minnesota.
Jones began serving as the interim head of the ATF in 2011, and the appointment was made permanent in 2013.
