NFL: Indianapolis 31, Tennessee 9

NASHVILLE, Oct. 12 (UPI) -- Peyton Manning was 36-of-44 passing for 309 yards and three touchdowns Sunday and the Indianapolis Colts remained unbeaten with a 31-9 win over Tennessee.

Titans quarterback Kerry Collins was 19-of-32 passing for 164 yards and one interception. Vince Young took over for Tennessee (0-5) with 7:26 left to play.

After starting last season 10-0 and winning the AFC South title, the Titans are off to their worst start since they opened at 0-5 in 2006.
