Charles Tillman prepares for Kyle Orton

LAKE FOREST, Ill. -- Chicago Bears cornerback Charles Tillman said Monday if the Kansas City Chiefs start recently acquired quarterback Kyle Orton on Sunday at Soldier Field, it likely will be a condensed game plan and a challenge for Orton.

Orton requested his release from the Denver Broncos last week after Bears quarterback Jay Cutler injured his thumb. It was thought Orton wanted to land in Chicago, where he played from 2005-08, but the Chiefs claimed him on the waiver wire before the Bears could get him.

With Matt Cassel on injured reserve, Kansas City was forced to start Tyler Palko against the Pittsburgh Steelers on Sunday night. In his second start, Palko went 18-for-28 for 167 yards and three interceptions. He has seven turnovers in two games. Still, it might be tough to integrate Orton into the Chiefs offense.

"I would think it'd be pretty condensed," Tillman said. "It's hard enough -- not to say he's coming off the street -- but to get a guy coming from another team and obviously a quarterback with the checks. Everyone runs a different type of an offense.

"Yeah, I'd think it'd be pretty hard. I'm sure if he does play, it'll be pretty condensed. They'll make it easy for him."

Chiefs coach Todd Haley did say Monday that Palko remains the
starter, but Orton will get plenty of repetitions with the
first-team offense this week.

Despite their 25-20 loss to the Oakland Raiders on Sunday, the Bears (7-4) are in prime wild-card position. But Tillman said the focus is entirely on Kansas City.

"I don't think you can look ahead to that now," Tillman said. "You got to take it one game a time, because I really feel starting to look toward a wild card spot, we'll lose games that are in front of us.

"We got to focus on the task at hand. The wild card, that's the telescope, we're looking at that from a distance. Right now we're looking through a microscope, that's Kansas City right now."

If Kansas City starts Orton, the Bears will be familiar with his work. He threw 33 touchdowns in 30 career games with the Bears, going 21-12 as a starter. He was traded to Denver in the 2009 Cutler deal and then benched for Tim Tebow this season.

Tillman said there's no extra emphasis in facing Orton, who was well-liked by his teammates.

"It'll be good to see him, like 'Hey, what's going on? Throw me a pick please,'" Tillman said. "It'll be nice to go against him, but there's no extra motivation or anything like that."
