(The Sports Xchange) - The Dallas Cowboys activated defensive end David Irving from the reserve/exempt list and he is expected to play in Sunday's game against the Green Bay Packers.


Irving returned to practice Wednesday after a four-game suspension for violating the league's substance-abuse policy.


Irving, 24, replaces defensive end Charles Tapper, who was placed on injured reserve Thursday after suffering a broken bone in his foot in Wednesday's practice.


Irving was named NFC Defensive Player of the Week after last year's meeting against the Packers, recording a sack and forcing three fumbles in the Cowboys' win at Lambeau Field.

Bradford missed the last three games with a knee injury but returned to practice on Thursday.
