Last week
Adam Vinatieri kicked a 52-yard field goal to lift the Colts to an 18-15 home win over his former team, the Patriots. ... Pittsburgh became the first team to intercept Jason Campbell this season -- picking him off twice in a 23-6 win at Washington on Monday Night Football.
Keep your eye on ...
Indy's front line: Finally completely healthy, the Colts' offensive line has not allowed a sack on Peyton Manning in its last three games. It will be challenged to continue that trend against Pittsburgh, which has a league-leading 32 sacks, including seven against Washington on Monday night.
Pittsburgh's linebackers: Five of those seven sacks came from Steelers linebackers. James Farrior, James Harrison, Lawrence Timmons and LaMarr Woodley combined for 23 solo tackles against the Redskins. Woodley and Harrison have combined for 15.5 sacks in Pittsburgh's last six games.
Parker's participation: Willie Parker returned last week after a knee injury kept him out of Pittsburgh's previous four games, but now a shoulder injury has put Parker in jeopardy of missing Sunday's game with Indianapolis. If Parker can't go, the Steelers will be confident in the ability of backup Mewelde Moore, who has 314 rushing yards, and four touchdowns in four games as Pittsburgh's starter.
