Austin watched Thursday's practice from the sideline while wearing a walking boot on his injured left foot. On the official injury report, he's listed as "did not participate" once again.
More will be known about Austin's status on Friday, when the team has its final practice of the week before Sunday's game against New Orleans.
Also missing practice for the second day in a row were cornerback Janoris Jenkins (back) and running back Daryl Richardson (thigh). Guard Harvey Dahl (knee) joined that group on the not practicing list.
Cornerback Brandon McGee (foot) returned to practice as a full participant.
