A few thoughts on the second half of “Bill Belichick: A Football Life,” just as soon as I figure out how to change the clock on the dashboard of my car ...

FOXBORO -- Defensive tackle Albert Haynesworth missed his first practice with the Patriots since Sept. 10, sitting out the Thursday session with what the team referred to as a back injury. However, cornerback Kyle Arrington, who was held out of practice on Wednesday (he was listed as having a concussion) returned to practice in a limited role. Here's the rest of the Patriots injury report for Thursday:

Did Not Practice
S Patrick Chung (hand)
TE Dan Gronkowski (hamstring)
DT Albert Haynesworth (back)
TE Aaron Hernandez (knee)

FOXBORO -- Albert Haynesworth and Patrick Chung were among six Patriots players not spotted at the beginning of a rainy practice on the lower grass field outside Gillette Stadium Thursday afternoon. 

Chung reportedly had thumb surgery on Wednesday and is not likely to play this Sunday in Orchard Park, N.Y., as the Patriots play the Bills. Also missing on Thursday were defensive lineman Mike Wright (concussion), tight ends Aaron Hernandez (knee) and Dan Gronkowski (hamstring), and offensive tackle Sebastian Vollmer (back). 

FOXBORO -- The Patriots signed linebacker Jeff Tarpinian off the practice squad on Thursday and released linebacker A.J. Edds. Taking Tarpinian's spot on the practice squad is defensive back Josh Victorian. 

Edds was signed by the Patriots in the week prior to the season opener in Miami. He did not have a tackle against the Dolphins but made one tackle and assisted on another in the Week 2 win over the Chargers. 

San Diego defensive tackle Antonio Garay has been fined $15,000 for his hit in Patriots quarterback Tom Brady on Sunday, according to ESPN's Adam Schefter. Garay, who appeared to dive at the back of Brady's knees, wasn't flagged for the play. For more Patriots news, check out weei.com/patriots.

Fox analyst and former NFL coach Brian Billick was a guest of the Dennis & Callahan show on Thursday. Billick was asked what an opposing team has to do in an attempt to slow down Tom Brady. The reigning MVP has thrown for 940 yards and seven touchdowns in the first two games of 2011.

FOXBORO -- One year ago Thursday, Kevin Faulk was placed on injured reserve after suffering a torn ACL injury in a Week Two loss to the Jets.

In the wake of Sunday's win over the Chargers, Patriots safety Patrick Chung has undergone surgery on his right thumb, according to ESPN Boston. Chung appeared to suffer an injury to his hand or arm in the second half of Sunday's game, and missed a sizable portion of the action in the second half. He is second on the team with 14 tackles.
