FOXBORO - Tom Brady and former Patriots backup Rohan Davey had a brief exchange during warmups. Brady traipsed over the Cardinals side of the 50 to head butt Davey as he warmed up. Davey and Brady embraced and then talked for about three minutes before going their separate ways.

Davey is currently the fourth quarterback on the Cardinals depth chart behind Kurt Warner, John Navarre and Matt Leinart who's been in camp for about 15 minutes.
