Peterson, 33, is coming off a season in which he rushed for 529 yards in 10 games. After that, Samaje Perine and Byron Marshall have been banged up as well. Peterson is not guaranteed the starting job with Washington and will likely share responsibilities with Rob Kelley and third-down back Chris Thompson. The team also brought in veterans Jamaal Charles and Orleans Darkwa over the weekend.
