With three of the four top Ravens running backs in John Harbaugh's dog house, it isn't necessarily a bad idea for the organization to bring in one more.

After trying out at the their rookie minicamp last week, running back Fitzgerald Toussaint will sign an undrafted free agent contract with the Ravens, reports The Baltimore Sun.

Toussaint played college football at the University of Michigan and ran for 1,041 yards and nine touchdowns in 2011. However, his previous two seasons didn't go as planned.

He sustained a major leg injury near the end of the 2012 season and played behind arguably the worst offensive line in the history of Michigan football, even though draft picks Taylor Lewan and Michael Schofield bookended the Wolverines at both tackle spots. In fact, in an overtime loss against Penn State, Toussaint carried the ball 27 times for just 27 yards.

Even so, Toussaint will still have an opportunity to put out some practice film in a worst case scenario. He'd be seen as nothing more than a potential practice squad player at this time.
