MEQUON, Wis. (AP) -- Holdout running back Steven Jackson missed his fourth day of St. Louis Rams training camp today, but he's keeping in touch.

Coach Scott Linehan hasn't spoken with Jackson since Wednesday, when he was informed there would be an empty seat on the team's flight to Wisconsin. But he has been text-messaging with Jackson, who is apparently eager for updates while making a stand for a new contract.

Several teammates also have been in contact with the player.

Jackson is a bruising runner coming off his third consecutive 1,000-yard season despite missing four games last year. He is entering the final year of a deal he signed after the Rams took him in the first round of the 2004 draft.
