That's a wrap: Day 10 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:

Ty Warren's injury needs further evaluation. Unsolicited, head coach Bill Belichick opened his press conference by noting that offensive lineman Nick Kaczur (back) and defensive end Ty Warren (reportedly his hip) have missed a significant number of practices and that their injury situations require further evaluation. Belichick said other injured players were closer to the "day to day" category, which means that Kaczur and Warren seem to be facing more serious situations. Kaczur has told teammates that he has a significant back injury that could threaten his 2010 season. Elsewhere on the injury front, safety Josh Barrett, who was claimed off waivers from the Broncos, is scheduled to undergo shoulder surgery.

Roster moves; local product Farnham released. Addressing depth concerns on the interior of the offensive line, the Patriots signed third-year veteran Darnell Stapleton, formerly of the Pittsburgh Steelers. The team also signed cornerback DeAngelo Willingham. Both are longshots to earn a roster spot, but add depth entering the first preseason game Thursday. To make room on the roster, the team released receiver Buddy Farnham and defensive lineman Adrian Grady. Farnham grew up in Andover, Mass., and played at Brown University, and was hoping to beat the odds to stick on the practice squad.

Lot of chatter on the Saints. With the Saints coming to town for joint practices on Tuesday and Wednesday, Bill Belichick broke down how the practices will unfold. Players seem excited about the change of pace. "This will be great for the fans to see. I think there will be a pretty good buzz throughout practice this week," veteran left tackle Matt Light said.

Officials in town. Players listened to a presentation from officials on the NFL's new rule changes. One of the big ones is the new positioning of the umpire behind the quarterback, and how that could potentially slow down the team's no-huddle attack because it will take the umpire longer to spot the ball.
