NFL: Johnson runs for 117 yards, Titans rout Rams 47-7

NASHVILLE, Tenn. — Chris Johnson ran for 117 yards and two touchdowns and also took a short pass 66 yards for another score and the Tennessee Titans kept their faint playoff hopes alive by routing the woeful St. Louis Rams 47-7 Sunday.

The Titans (6-7) must win out and get plenty of help. But they started a three-game homestand by handing the struggling Rams (1-12) a fifth straight loss even with Vince Young sidelined by a strained right hamstring most of the game.

Young started despite an achy right knee and played well until pulling up at the end of a 44-yard run — the longest of his career — midway through the second quarter. He left with a 14-0 lead and watched from the sideline as Kerry Collins finished off the win.

The Titans intercepted five passes they turned into 20 points, ruining the NFL debut of rookie Keith Null as St. Louis' third quarterback this season.
