Here's a matchup to watch in the Week Two game between the Patriots and Chargers:

Patriots DT Albert Haynesworth vs. Chargers OLG Kris Dielman

In addition to being a crucial matchup for the Patriots to win as they attempt to keep QB Philip Rivers in check, this will be a fantastic football battle to keep an eye on all Sunday afternoon.

You have Haynesworth, one of the league's most dominating defensive tackles, who is trying to find his old self in New England, against Dielman, a four-time Pro Bowler.

In Haynesworth's first action against Miami, he played 32 snaps, according to ESPN Boston, and made an impact. Haynesworth had two tackles and drew two holding penalties from Dolphins OLG Richie Incognito.

The Patriots will be doing everything in their power to rattle Rivers. They sacked him two timesand picked him off once in last season's meeting, and one of the reasons to get Haynesworth was to spark an interior pass rush. Paired with DT Vince Wilfork, if Haynesworth can win his battles against Dielman and push into Rivers, who releases the ball quickly, he can alleviate some of the pressure on the secondary, which gave up more than 400 passing yards to Chad Henne in Week One.

Haynesworth v. Dielman will be a great heavyweight battle, and also a big test to see where Haynesworth is in his attempted return to stardom.
