Kerney, though, says winning the sack title is not of significant concern to him. "I am not in this for individual titles," Kerney said. "Certainly I go into Atlanta expecting to play the entire game. If somebody else decides differently, I am OK with what's best for the team. Sack title, if I hang on, that would be great icing on the cake. If I don't, I am not going to sweat it. Certainly, I know there is not a big silver trophy for that."
Atlanta, which has lost six consecutive games, is among the bottom third in the league with 45 sacks allowed, including two on Sunday.
Meanwhile, Williams faces a Jacksonville offense that has relinquished just 29 sacks. And Allen's Chiefs face the New York Jets, who have permitted 48 sacks, four in Sunday's loss to Tennessee.
Beyond that, Kerney has the inspiration of playing before the fans who rooted for him for eight years.
"It would be great to put on a good performance there," Kerney said. "I know the fans who have been so good to me for so long there expect a good performance from me. I like to think that is what they were used to for eight years and what they will get next week."
--QB Matt Hasselbeck needs 23 yards passing to set the single-season Seattle record. It is unlikely that Hasselbeck plays the entire game Sunday in Atlanta because the outcome has no impact on Seattle's season.
--RB Shaun Alexander, who broke a bone in his wrist in the first week of the season, said he felt better on Sunday than he has all season. Alexander had 73 yards, the most he has produced since Week 4.
--WR D.J. Hackett, who has missed three games with a high-ankle sprain, will practice this week. But it is unclear if he will play against the Falcons.
--WR Bobby Engram, who has five touchdowns, needs two more to set a career high. He already has career highs in yards (1,082) and receptions (90).
--DE Darryl Tapp was credited with a half sack against Baltimore. It was his first sack in four weeks.
--LB Julian Peterson needs one sack to set a career high. Peterson currently has 9.5 sacks.
--DT Rocky Bernard continues to suffer from a sore groin. It kept him out of Sunday's game against the Ravens. It is unclear if he will play against Atlanta.
--CB Josh Wilson, who suffered a quad injury three weeks ago and has not played since, is not likely to play against Atlanta on Sunday.
--LB Lofa Tatupu has 106 tackles, the first player in franchise history to record three straight 100-tackle seasons.
