GREEN BAY -- Mike McCarthy has his priorities for what he wants the Packers to work on this week heading into their second preseason game.

"We didn’t tackle very well against Philadelphia, we didn’t break tackles against Philadelphia, our run offense wasn’t what it needed to be, and our ball security as a whole was unacceptable," McCarthy said prior to the Packers returning to the practice field on Tuesday.

Regarding ball-security, McCarthy complimented the defense for getting the ball out a number of times, and being in position for more than the four turnovers the unit generated. But the equation came out nearly even with the offense's struggles protecting the ball, and that's not what McCarthy is looking for.

"We need to improve that," he said of the fundamentals of both tackling and ball security. "You can throw a band-aid on it, and say it's preseason game one, and around the league you see a lot of that going on, but that’s not how we’ll go about it."

The Packers have open practices at Ray Nitschke Field scheduled for Tuesday and Wednesday. Tuesday's workout will focus on a lot of corrections from the Eagles game because the first practice after the preseason opener, on Sunday, was focused on preparing for Week 1 vs. Seattle.

On the injury front, McCarthy said offensive lineman Don Barclay (ankle), WR Malachi Dupre (concussion), CB Damarious Randall (concussion) and LB Vince Biegel (foot, PUP) all would not practice this week nor play at Washington on Saturday night.
