Austin was traded to the Cowboys in April of last year from the Los Angeles Rams to add speed to the young offense. In seven games last season, Austin caught eight passes for 140 yards and two touchdowns, and he also returned punts.

Dallas also added Covington to bring more depth to the defensive line after his stint with the Texans. The 300-pound lineman played at Rice University and was drafted in the sixth round in the 2015 draft.
