With the NFC North up for grabs, the Chicago Bears snatched control.

Charles Tillman intercepted Jeff Garcia's across-the-body pass and returned it 22 yards for a touchdown with 8 minutes 43 seconds left in overtime Sunday, putting Chicago atop the division with a 19-13 win over the Detroit Lions.

Garcia, making his second start in place of Joey Harrington, rolled right and tried to throw back across the field to Mike Williams. Tillman stepped in front of the soft toss and raced untouched to the end zone, where he was mobbed by teammates.

"The ball was floating," Tillman said. "But my eyes weren't big until I caught it and knew I would score."

It was a big win for Chicago (4-3) not only because the Bears broke a first-place tie with Detroit (3-4), but also because they secured a head-to-head tiebreaker over the Lions, whom they beat 38-6 in an earlier meeting.

"This is my third year in the league and it's my first time in first place," Tillman said. "It's feeling pretty good. I'm going to savor the moment."

Charles Tillman won't let go of the ball he intercepted and returned for a score in overtime to give Chicago sole possession of first in the NFC North.
