Special teams standout Brad Smith, who has played all over the field in his NFL career, will pay a visit to the Lions on Tuesday, reports Dave Birkett of the Detroit Free Press. While Smith has seen time at quarterback, running back, and wide receiver during his NFL career, and was a very productive kick returner a few years ago, his primary contributions at this point in his career will come in kick and punt coverage.

Meanwhile, a Lions free agent, defensive tackle C.J. Mosley, is visiting an unknown team today, per Birkett. There were conflicting reports last week on whether Detroit has interest in re-signing Mosley, and Birkett notes that while the Lions have engaged with the defensive lineman about a possible return, no agreement is imminent.

Here’s more from out of the NFL’s two North divisions:

• Ravens quarterback Joe Flacco would like to play in the NFL until he’s at least 40 years old, as he tells Jamison Hensley of ESPN.com. Of course, we should probably take Flacco’s comments with a grain of salt at this point, considering he just turned 30 earlier this year.
• While the Steelers may not adjust Antonio Brown‘s contract this year, Jeremy Fowler of ESPN.com, with the help of former NFL salary cap analyst J.I. Halsell, attempts to identify a potential extension scenario that could work for both sides.
• Judge David Doty will hear the NFLPA’s motion to hold Roger Goodell in contempt of court in the Adrian Peterson case on August 13, tweets Ben Goessling of ESPN.com. Doty ruled in favor of the NFLPA back in February, granting the union’s motion to overturn the league’s decision on Peterson’s suspension, but the NFL didn’t reinstate the Vikings running back until mid-April.
• Aaron Wilson of the Baltimore Sun passes along word of a couple auditions taking place this week, reporting (via Twitter) that center/guard Ben Gottschalk is trying out for the Packers today and former Hawaii defensive end Beau Yap is working out for the Bengals tomorrow.
