(MCT) — NASHVILLE, Tenn. — Setting his clock back six years Sunday at LP Field, Bears linebacker Brian Urlacher stayed stride for stride with Titans running back Chris Johnson covering a deep pass route down the sideline.

Johnson, who once clocked 4.24 seconds in the 40-yard dash, boasts some of the fastest feet in the NFL. Urlacher, 13 seasons removed from the days when he played defensive back in college, possesses a balky left knee that has been the source of international intrigue and considerable doubt.
