The LeGarrette Blount and Le'Veon Bell duo is off to a rough start.

Just hours before landing into Philadelphia, Pennsylvania, the two were arrested and charged with marijuana possession after a police officer saw the smoke coming from their car. A female passenger accompanied the two backs. Bell was driving the Camaro, and he will be charged with DUI. The Steelers play the Eagles Thursday night in Philadelphia in a preseason game.

No decision has been made by the NFL yet, but a suspension is likely and expected.

This comes at a terrible time for the Steelers because the draft is over and much of the free agents are off the board. Still, there is talent to be found even in the middle of August. Here are some notable running backs who are still free agents.

Michael Bush

Bush has been in the league since 2007, so he's an experienced back. He played four seasons with the Oakland Raiders where he ran for 2,642 yards on 4 yards per carry. Pretty impressive considering it was the Raiders offensive line. In 2011, he ran for a career high 977 yards and seven touchdowns, while having over 400 receiving yards. He's not an elite back, but the Steelers might want to give this guy a call.

Bush is also a very large back, who can be used in goal line situations.

Willis McGahee

McGahee is by far the most established back on this list. The 32-year-old veteran has rushed for over 1,000 yards four times in his career, on three different teams. He has over 8,000 career rushing yards and rarely fumbles. But last season was a disaster for McGahee. Injuries and a poor Cleveland Browns system result in career lows across the board. Maybe it was a fluke. It was, after all, the Browns offensive line.

McGahee is an established veteran who is worth a low dollar risk.

Tashard Choice

Choice is a versatile running back. He's not an every down back who can carry the load, but his receiving skills can help a team. With the Dallas Cowboys, Choice averaged 4.6 yards per carry and did a lot of damage out of the backfield. Choice has only fumbled seven times in 88 career games. Choice hasn't been playing his best football lately with the Buffalo Bills or Indianapolis Colts, but his high speed and athleticism can help the Steelers.

LaRod Stephens-Howling

Stephens-Howling isn't going to make a huge difference, but if the Steelers want to sign a player for the lowest amount, he could be their guy. He's only 27 years old, and he did play for the University of Pittsburgh. In 2012, Stephens-Howling had 463 total yard yards but last season had an ACL injury. Stephens-Howling is also a very good kick returner who has multiple 1,000 yard kick return seasons.
