8:30pm: In addition to Johnson, the Cowboys will also audition Christian Ponder, sources tell Charean Williams of the Star-Telegram (on Twitter). Matt Flynn will also audition on Tuesday, per Josina Anderson of ESPN.com (on Twitter).
Meanwhile, Kyle Orton is not a real possibility for the Cowboys thanks to his fractured relationship with the club and his own bad personal relationship with Romo, Ed Werder of ESPN.com tweets.
5:05pm: The Cowboys have reached out to a few veteran quarterbacks, according to CBSSports.com’s Jason La Canfora (on Twitter). Dallas called reps for both Jason Campbell and Josh Johnson, among others, per La Canfora. Johnson will work out for Dallas, but Campbell will remain in his state of quasi-retirement for now.
While Dallas scopes out the market for signal callers, La Canfora (link) hears that the Saints do not plan to do the same at this time. Of course, that could change with starter Drew Brees potentially out for several games.
In related news, coach Jason Garrett says they’ll consider putting Tony Romo on IR-DTR as the week goes on, James Palmer of NFL.com tweets. Nothing is decided on that front yet, however, and the upside right now is that Romo’s tests revealed zero ligament damage. Romo fractured his clavicle on Sunday, the same injury that caused him to miss the final 10 games of the season in 2010.
