JACKSONVILLE, Fla. (AP) -- The Tennessee Titans easily won the battle of backup quarterbacks against the Jacksonville Jaguars in a 30-3 victory Monday night that put them in a three-way tie atop the AFC South.

Vince Young was knocked out of game on the second series with a sprained left knee, and Kerry Collins led the Titans (4-2) on five straight scoring drives. The Titans didn't have to punt over the final 43 minutes of the game.

Chris Johnson scored on a 35-yard run with 1:40 left to finish with 111 yards on 26 carries.

David Garrard left the game late in first half with a concussion and was replaced by Trent Edwards. On three drives inside the Titans 20, the Jaguars (3-3) turned it over twice and had to settled for a short field goal by Josh Scobee.
