Justin Forsett showing signs of wearing down

The career year for Baltimore Ravens running back Justin Forsett is ending on a down -- and unfortunately predictable -- note.

In the past two games, Forsett has totaled 68 yards rushing and has been held under three yards per carry, an indication that the heaviest workload of his seven-year career is taking a toll. There have been signs of the NFL's fifth-leading rusher wearing down, from a knee injury a couple of weeks ago to an ankle injury on Sunday which forced him to miss the final nine minutes of the game.

"I'm fine. I'm ready to go," Forsett said after being held to a season-low 19 yards. "The defense did a great job, stopping us and stopping the run. Sometimes it's like that. We have to find a way to execute and win games. We just didn't do that today."

Forsett has now carried the ball 218 times, which ranks 10th-most in the NFL this season. That's also 100 more carries than he's received in any of his previous six seasons.

Teams are beginning to figure out that stopping the Ravens' run game throws everything out of whack for the Ravens' offense. The Ravens are 8-1 when they rush for over 120 yards, and they're 1-4 when they are held under 100 yards.

The Ravens managed 33 yards on the ground against the Houston Texans, which was only ranked 14th against the run.

"If we are not getting our running game going, it is going to affect us," quarterback Joe Flacco said. "Our running game wasn't working for a reason. They were playing physical and they were playing well up there."

The Ravens don't have many options outside of Forsett, especially after rookie Lorenzo Taliaferro was placed on injured reserve with a foot injury. On Sunday, undrafted rookie Fitzgerald Toussaint replaced Bernard Pierce as the No. 2 back and finished with 11 yards on four carries.

Getting the ground game on track is essential Sunday against a Cleveland Browns team that ranks near the bottom of the NFL in run defense.
