The Vikings likely will keep only three running backs so the competition for that third spot will be hotly contested in camp.
Adrian Peterson and Toby Gerhart are the top two running backs. Competing for that third spot will be Albert Young, Ryan Moats, Darius Reynaud and Ian Johnson.
Young is entering his third season with the Vikings and has a firm grasp of the offense, so he might be the early favorite.
"I love Albert," coach Brad Childress said. "He knows it forward and backward."
