Warm-up time in San Diego

Posted by ESPN.com's Bill Williamson

SAN DIEGO -- Random pre-game thoughts:

It is clear skies and 72 degrees in San Diego. Perfect weather conditions are expected at game time.

San Diego running back Darren Sproles is on the field and is engaging in full warm-ups. He is expected to play a key role for the Chargers with star LaDainian Tomlinson likely limited with a lingering turf toe injury.

San Diego left tackle Marcus McNeill is expected to play for the first time this season. He has missed the first two games with a neck stinger.

Quarterbacks Brett Favre and Philip Rivers are back in their respective locker rooms after warming up early. The players chatted for several minutes. Rivers has said Favre has long been his favorite quarterback.

There are plenty of No. 4 jerseys in the stadium -- and some of the in Jets' colors. There are many of Favre's Green Bay jerseys in the house.
