Leonard Fournette's return from injury is on hold.

NFL Network Insider Ian Rapoport reported Sunday the rookie is inactive versus the Cincinnati Bengals for a violation of team rules, according to a source informed of the situation.

There is no word on what rule the running back violated.

"Leonard Fournette is not playing in today's game due to an infraction of a team rule," coach Doug Marrone said in a statement 90 minutes before kickoff. "This has been addressed internally and further details will not be made public."

Fournette missed the Jags' Week 7 win with an ankle injury. He was slated to return after healing over the team's bye last week.
