NFC North links: Coach defends A.J. Hawk

Chicago Bears

Former Bears quarterback Nathan Enderle, a fifth-round pick in 2011 who was released last week, has signed with Jacksonville. His exit gives Matt Blanchard, an undrafted rookie from Wisconsin-Whitewater, a chance to be the fourth quarterback in training camp.

Desmond Clark, 35, who spent the final eight of his 12 NFL seasons with the Bears (2003-10) has become a real estate professional, writes Larry Mayer of the team's website. Clark ranks second all-time in franchise history among tight ends with 242 receptions, trailing only Hall of Famer Mike Ditka.

Detroit Lions

The Lions claimed cornerback Dontrell Johnson off waivers from the Jacksonville Jaguars, and released safety Alonzo Lawrence, writes Dave Birkett of the Detroit Free Press.

The Lions signed quarterback R.J. Archer, who played for the Georgia Force in the Arena Football League this season. He'll compete with undrafted free agent Kellen Moore for the No. 3 job.

Receiver Nate Burleson says quarterback Matthew Stafford has a rocket arm.

Running backs Jahvid Best and Mikel Leshoure are walking similar paths early in their careers, writes Mike O'Hara of the team's website.

Green Bay Packers

Inside linebackers coach Winston Moss insists that former first-round pick A.J. Hawk didn't have a down season in 2011, writes Tyler Dunne of the Milwaukee Journal Sentinel.

After four days of NFL Broadcast Boot Camp training, former Packers tackle Mark Tauscher was one of two players chosen to serve as a television studio analyst for an NFL regular-season Sunday, working on-air for one of the league’s United Kingdom television partners, writes Bob Wolfley of the Journal Sentinel.

Minnesota Vikings

Quarterback Christian Ponder and coach Leslie Frazier feel Ponder made a lot of progress during the nine weeks of offseason work, which culminated with Thursday's final minicamp practice.
