Steven Jackson will play. NFL Network reported moments ago that the St. Louis Rams running back tested out his groin on the field for warmups. Apparently he passed the test just fine, and will be active for Sunday's game against the Chicago Bears.

But how active is active?

For the first time in years, the St. Louis Rams have a viable option behind Jackson on the depth chart, rookie running back Daryl Richardson. The seventh-round pick took over for Jackson last week against the Redskin, running well except for one fumble that did not end up being a problem for the Rams.

Richardson could be a part of a trio of rookie who carry some of the load, along with Isaiah Pead and Terrance Ganaway. Of course, with Jackson active, one of those two is liable to be sitting out this game.

It's a safe bet that Richardson's workload will increase this week, even with a healthy Jackson. That was the plan all along, only they had Pead penciled in to do the part-timing.

If you're leaning on Jackson for your fantasy football team, you might want to find other options.
