Brandon Marshall caught three scoring passes en route to a 122-yard performance Sunday, keying the Chicago Bears\' 51-20 waltz over Tennessee. Marshall finished with nine grabs while Charles Tillman led Chicago\'s stifling defense with nine tackles and forced four fumbles as the NFC Central-leading Bears (7-1) reeled off their seventh straight win. Brian Urlacher returned an interception for a touchdown while Matt Forte ran for 103 yards with a score in the triumph. Jay Cutler completed 19-for-26 passes for 229 yards and a trio of TD passes for Chicago. The Titans (3-6) were led by Chris Johnson with 141 rushing yards and a touchdown on 16 carries. But the Tennessee star also lost two fumbles in the setback. Matt Hasselbeck was held to 20-of-35 through the air for 194 yards, a touchdown and an interception for the Titans.
