Imagine a shortstop having worked with the same second baseman for 13 seasons and then being asked to turn double plays with a rookie, and you've got an idea how Sebastian Janikowski feels.

Marquette King isn't technically a rookie, having spent last season on injured reserve, but he's not Shane Lechler, either.

Six games into the season, Janikowski is still getting used to having someone other than Lechler as his place-kick holder as the Raiders host the Pittsburgh Steelers on Sunday at O.co Coliseum.

In a 24-7 loss to the Kansas City Chiefs preceding the bye week, Janikowski had his most surprising miss yet -- a 51-yard attempt that came up short in Arrowhead Stadium, his favorite kicking venue.

"I was kicking the ball great in warmups," Janikowski said Friday. "I didn't miss anything. I just love that place. There's something about Kansas City."

And then?

"Right when it hit his foot, I heard it," long-snapper Jon Condo said. "He didn't make good contact."

"I was surprised," Janikowski said. "I didn't hit it real good, and I kind of toed it."

That makes four misses for Janikowski in six games. In Week 1, he missed wide left from 48 yards after not having failed from 49 yards and in since 2011. Janikowski was 4 for 5 the following week against Jacksonville, but was wide left from 35 yards out, his first miss under 40 yards in 50 attempts.

Janikowski missed from 52 yards against Washington.

He missed only three field goal attempts last season, all from 50 yards or longer.

Raiders coach Dennis Allen, who like most everyone thought Janikowski was back on track with field goals of 47 and 50 yards without a miss in a win over San Diego, was extending another vote of confidence to his struggling kicker.
