Rams' Jackson limited during warm-ups

ST. LOUIS -- Steven Jackson came out briefly and jogged lightly during early warm-ups at the Edward Jones Dome.

Jackson made no hard cuts. He did not accelerate hard. He did nothing that made me think he was ready to go full speed against the Seattle Seahawks or any NFL team. That was just my impression. Jackson could still play; the Rams have not yet declared their inactive players.

But if Jackson starts and plays extensively, I'll be surprised.

The Rams have until 90 minutes before kickoff to name their inactive players.

ESPN's Adam Schefter expects the Rams to keep Jackson active for the game even though the team is unsure how much Jackson will play.
