"Under the rules established by the NFL Collective Bargaining Agreement, we have seven days to make this decision, which ends at 11 p.m. CDT next Wednesday (April 20)."
If the Packers decline to match Minnesota's offer, Green Bay will receive a fifth-round draft pick from the Vikings as compensation.
NFL teams have until April 15 to make offers to restricted free agents. The Packers had tendered Kampman at one year, $656,000. He became a starter in 2003 when Joe Johnson suffered a season-ending injury. Last year, Kampman started all 16 games and finished with 71 tackles and 4.5 sacks, more than his previous two seasons combined.
"There's been significant interest in Aaron," Neil Cornrich, Kampman's agent told the Milwaukee Journal Sentinel last week. "Numerous teams have called and inquired about his status. It's very flattering and is the result of what Aaron has accomplished over his first three years in the league."
Just one restricted free agent changed teams last year and Cornrich was his agent. Pittsburgh declined to match New England's one-year, $1.3 million offer to defensive end Rodney Bailey. This year, Denver didn't match a five-year, $15 million offer from Seattle to cornerback Kelly Herndon and Minnesota announced last Thursday that it would not match a two-year, $1.5 million offer from Cleveland to safety Brian Russell.
