GREEN BAY -- The Green Bay Packers made a trade with the Carolina Panthers Monday, but fans hoping for a blockbuster involving Pro Bowl defensive end Julius Peppers will be utterly disappointed.

The Packers dealt long-snapper J.J. Jansen, who missed all of last season with a knee injury, to the Panthers for what the team called a "future conditional draft pick." By definition, the pick can't be in this month's draft, since it's contingent on whether Jansen makes the Panthers' roster. There's likely a provision about how many games Jansen plays or spends on the roster during the regular season as well.

A league source said the pick is a seventh-rounder in 2011.

The Packers signed Jansen last spring as an undrafted free agent from Notre Dame. He beat out Thomas Gafford one week into training camp to win the long-snapping job but suffered a torn lateral collateral ligament his left knee in the exhibition finale against the Tennessee Titans and spent the year on injured reserve.

Jansen, who has been participating in the Packers' offseason program, was put on IR on the final roster reduction to 53 players, even though he might've been able to return from the injury during the season. The Packers replaced him with Brett Goode, who was signed off the street and snapped well in all 16 games.

The Panthers' long-snapper since 2001 has been 36-year-old Jason Kyle, an unrestricted free agent who remains unsigned.
