Allen Park — During the offseason, Lions wide receiver Corey Fuller said his brother Kyle joining the division-rival Chicago Bears provided extra motivation for him to make the 53-man roster.

Corey made the Lions and is playing a significant role as the No. 4 receiver, but with how his brother has started his rookie season for Chicago, he's become even hungrier.

Kyle, a first-round cornerback, already has three interceptions this season, which leads the NFL. It's also two more catches than Corey has, though his one last week was a 52-yard gain.

The brothers talk on the phone regularly and share tips, and Corey keeps things in perspective when cheering for Kyle.

"While he's playing, I'm his biggest fan," he said. "It's kind of tough sometimes because he's doing so good, and it's helping Chicago. So some people can take that the wrong way when I'm actually just cheering for Kyle."

Kyle started the season as the Bears' No. 3 cornerback, but with Charles Tillman suffering a season-ending triceps injury in Week 2, he's already a starter. And with 19 tackles, three interceptions and two forced fumbles, Kyle has quickly overcome what's often a difficult learning curve for rookie cornerbacks in the NFL.

The Lions don't play the Bears until Week 13, a Thanksgiving matchup at Ford Field, but the trash talk between the brothers has already started.

"He actually told me he has something for me," Corey said. "I'm waiting to see what it is, but I'm not worried about it."

Corey said he's focused on the Jets this week and will worry about the Buffalo Bills next week, but he's excited for the chance to play against his brother.

"It'll be fun," he said. "I just know in the back of my mind I get to play my brother in an NFL game on Thanksgiving Day."
