GREEN BAY, Wis. -

After seeing the Seattle Seahawks get punished last week, Green Bay Packers coach Mike McCarthy knows teams can get in trouble for violating a league-wide ban on live contact during offseason workouts.

McCarthy acknowledged on Tuesday that he still isn't sure what level of contact can trigger a violation.

"Frankly, I don't know what the line is," he said.

Last week, the NFL punished the Seahawks after the league's management council and the players' union determined that Seattle violated the collective bargaining agreement's offseason workout rules by having live contact during one of the club's organized team activity sessions.
