"Leonard Fournette is not playing in today's game due to an infraction of a team rule," coach Doug Marrone said in a statement. "This has been addressed internally and further details will not be made public."
Among the reasons Fournette was deactivated for Sunday's game was that he missed the Jaguars' team photo on Oct. 24.
Fournette will be back next week, coach Doug Marrone said following the Jaguars' 23-7 victory.
Fournette is sixth in the NFL in rushing with 596 yards and has scored seven touchdowns in six games. Fournette missed the Jaguars' last game -- a 27-0 rout of Indianapolis -- with a sprained right ankle that he suffered late in the Jaguars' 27-17 loss to the Los Angeles Rams on Oct. 15.
