Fred Jackson's Updated 2013 Fantasy Outlook After C.J. Spiller's Ankle Injury

Buffalo Bills running back C.J. Spiller was forced to leave the game for a second straight week due to injury. With the dynamic playmaker struggling to showcase durability, Fred Jackson's fantasy value is quickly starting to rise.

Mike Rodak of ESPN provided an update on Spiller:

Last week, Spiller was unable to return after suffering a thigh injury. He's an explosive asset for the Bills offense and fantasy teams when healthy, but he can't seem to stay on the field. In turn, Jackson is picking up the slack.   

The veteran was averaging more than five yards per carry through three weeks. He's continued that trend in relief of Spiller against the Baltimore Ravens in Week 4, which makes him a very attractive option should he become more involved in the offense.

Jackson finished the game on Sunday with 87 yards and a touchdown on 16 carries.

However, as Rodak notes, Jackson also limped off the field, so his situation is certainly worth monitoring.

Moving forward, Jackson should be owned in all but the most shallow leagues, even if Spiller is cleared to return later in the game or ahead of Week 5. He's one injury away from becoming a major piece of a fast-paced offense.

If Spiller is forced to miss any significant period of time, he suddenly becomes a must-start option in fantasy leagues as the starter in Buffalo. Barring any serious injury of his own, Jackson will continue to produce.

Keep tabs on the situation, but Jackson is certainly worthy of a fantasy roster spot.
