Austin recorded just 24 catches for 244 yards in 11 games last season for the Dallas Cowboys, his eighth with the franchise that signed him out of Monmouth in 2006.
Over 106 NFL games, Austin has accumulated 301 receptions for 4,481 yards and 34 touchdowns. The 29-year-old New Jersey native will look to regain form from his career-defining campaigns of 2009-10, when he combined for 150 grabs, 2,361 yards and 18 TDs.
The signing is an insurance policy against the potential season-long loss of wideout Josh Gordon in the wake of his testing positive for marijuana last week.
