Halftime notes from Kansas City

KANSAS CITY -- Halftime notes from Kansas City, where the Raiders lead the Chiefs, 10-3:

Kansas City’s offense has been sluggish. Quarterback Matt Cassel looks out of sorts and uncomfortable. He has completed 6 of 17 passes for 52 yards.

Kansas City has three sacks. Linebacker Tamba Hali, fresh off a Pro Bowl-snub, has 2.5 sacks and now has 14.5 sacks this season.

Oakland has pressured Cassel often and has two sacks.

The Chiefs opened the game in the Wildcat formation, but used their base formation for the rest of the first half.

Kansas City, the No.1 rushing team in the NFL, has just 37 yards rushing. Thomas Jones has 12 yards and Jamaal Charles has 25 yards.

Starting for an injured Darren McFadden, Oakland running back Michael Bush has 55 yards rushing on 12 carries.

Oakland defensive lineman John Henderson was penalized 15 yards for late hit on Cassel. Henderson should expect a fine later in the week.

Oakland receiver Chaz Schilens caught his first touchdown of the season when he was wide open for a 5-yard score in the second quarter, giving the Raiders a 7-0 lead.

Oakland, the most penalized team in the NFL, has been flagged six times for 44 yards.

Former Kansas City coach Marty Schottenheimer is being inducted into the team's hall of fame at halftime.
