That's a wrap: Day 6 key storylines

FOXBOROUGH, Mass. -- At the end of every day of training camp, ESPNBoston.com will post one blog entry highlighting the key news of the day:

Writing the second chapter of this training camp story. After Monday's in-stadium night practice, the team's 10th of training camp, Tuesday marked a turning of the page of sorts. The team shifted into more situational work and at one point Bill Belichick called for the chains in two-minute work. Belichick was clearly leading the defense in the morning walkthrough, while linebackers coach Matt Patricia still worked with the headset to simulate getting the play-call and signaling it in to the defense.

No changes on injury situation with Nick Kaczur & Ty Warren. Left guard Nick Kaczur and defensive end Ty Warren remained out of practice, and safety Patrick Chung missed his first practice of camp. The Patriots had second-year player Ryan Wendell working at left guard, with Dan Connolly getting some time at center with the second unit. Kaczur has been battling a bad back and perhaps with that in mind, the team worked out free-agents Eric Ghiaciuc (center), Darnell Stapleton (guard) and Mark Ortmann (tackle), according to Adam Caplan of Foxsports.com. Ghiaciuc and Stapleton are with the Florida Tuskers of the United Football League.

Boosting the return game. Special teams coach Scott O'Brien met with reporters in the morning and when asked one unit he'd like to see improvement, he chose the kickoff return. Second-year receiver Brandon Tate will be key in making that happen, as he has worked as a primary kickoff returner in camp.

Birthday celebration for Tom Brady. As has become an annual tradition at training camp, Brady celebrated his birthday on the practice field, his 33rd. Fans and teammates sang "Happy Birthday" to him, and many fans brought signs wishing him well. Brady's father, Tom Sr., was on hand.
