Coming off their season-sweep over the Lions, the Bears stayed at home for a Week 10 interconference duel with the unbeaten Tennessee Titans.  With QB Kyle Orton nursing an almost-healed right ankle, QB Rex Grossman was given the start. In the first quarter, Chicago struck first as Grossman completed a 5-yard TD pass to rookie RB Matt Fort&#233;.  In the second quarter, the Titans responded with QB Kerry Collins completing a 10-yard TD pass to TE Bo Scaife.  In the third quarter, Tennessee took the lead as Collins completed a 12-yard TD pass to former Bears WR Justin Gage.  In the fourth quarter, the Titans increased their lead as RB LenDale White got a 2-yard TD run.  Chicago tried to rally as Grossman got a 1-yard TD run.  However, Tennessee's defense stiffened for the win.
