Austin has been slowed by hamstring issues the past two years after back-to-back 1,000-yard seasons in 2009 and 2010.
The 29-year-old Austin had just 579 yards in 10 games two years ago and played though hamstring problems last year to finish with 943 yards. He matched a career high with 10 catches in the opener this year against the Giants and has 15 catches for 125 yards.
Receiver and primary punt returner Dwayne Harris missed practice all week with a hip pointer and is listed as questionable.
Defensive end DeMarcus Ware (neck), cornerback Morris Claiborne (shoulder) and linebacker Ernie Sims are listed as probable.
