A friend of mine went to the game, and he reported seeing the following celebrities:

Dennis Quaid, who played a football player in the underrated film "Everybody's All-American." And, I recently saw a screening of his football movie "The Express" which was formula, but very good.

Someone that looks like they should be in the NFL, actor Michael Clarke Duncan (Sin City, Green Mile) was there. He's friends with a few people on the Chargers, and although he's from Chicago (therefore, a fan of Da Bears), I think the Chargers are now his second favorite team.

Another person told my friend they saw comedian Ray Romano, but then said "Although, that's a look that someone else could've had, and I just thought it was Romano. He was with some big wigs, though."

My friend didn't see this person, but a few of the papers reported him being there...Simpsons voice Hank Azaria, who has now been in a handful of movies where he's seen, too! Azaria was the guest of Jets owner Woody Johnson.
