The Vikings made three first round selections Thursday night, but they added a fourth in the form of defensive end Lawrence Jackson who was selected by the Seahawks in the first round of the 2008 Draft.  The Seahawks selected tight end John Carlson in the second round of that Draft and he is also on the current roster of the Vikings.

The deal for Jackson is reportedly of the one-year variety and he joins an already crowded depth chart that also saw rookie Sharrif Floyd added to it on Thursday night.  The hope is that this move is an attempt to have a top-notch rotation along the line, and not a sign that either Jared Allen or Brian Robison have more serious shoulder injuries than the team has let on.

He has generated 98 tackles, 19.5 sacks, four forced fumbles, and two recoveries in his five seasons with the Seahawks and Lions.  As another USC product joining the Vikings, Rick Spielman has continued to display an affinity for players coming out of that program.
