Fant reverted to the Cowboys' practice squad Tuesday, per the NFL's transaction log.
Fant was elevated to the Cowboys' active roster ahead of Monday's game against the Cardinals, when he played 11 snaps on special teams during Dallas' 27-17 loss to Arizona. The Cowboys are on a bye Week 10, so his next opportunity to be elevated to the active roster will be for Week 11 against the Raiders on Monday, Nov. 17.
