FOXBOROUGH -- Quick hits from Gillette Stadium:
Seau puts Patriots into oldest category: The signing of 40-year-old Junior Seau has put the Patriots into the top spot when it comes to oldest NFL rosters. The Patriots were the fourth oldest NFL team prior to signing Seau. The Patriots' defense was the 20th oldest in the league, but with Seau, it bumps up to 11th.
Preparing to tackle Chris Johnson challenge: Titans running back Chris Johnson leads the NFL in total yards from scrimmage (594), with defensive tackle Vince Wilfork calling him a tough challenge. "He can play some football," Wilfork said. "When he has the ball in his hands, everyone is at the point of attack. Between Johnson and [LenDale] White and the backup quarterback, [Vince] Young, it's going to be tough for us."
New jersey number for McKenzie: With veteran Derrick Burgess giving up No. 55 to Junior Seau, and switching to No. 53, it means that rookie Tyrone McKenzie also had his number changed. McKenzie, the team's third-round draft choice out of South Florida who is on injured reserve, is now No. 44.
Sands' locker still intact: The Patriots released defensive lineman Terdell Sands on Wednesday, making room for Junior Seau on the roster. But Sands' locker remains intact, which could be a sign that the team has plans to bring him back in the future.
