Spagnuolo: Jackson's back surgery 'minor'

Rams running back Steven Jackson underwent back surgery in April, Jim Thomas of the St. Louis Post-Dispatch reports.

What does it mean?

Coach Steve Spagnuolo told Thomas the surgery was a minor procedure and Jackson was fine.

Here's the thing about back injuries, however: They can be unpredictable and easily misunderstood. That was the lesson Seattle learned with Matt Hasselbeck.

The true test for Jackson will come during the regular season.
