Fullback Paul Smith is out this week and probably next week from injuries sustained in a wedge-busting collision that landed Smith and Detroit's Frank Davis in a hospital.

Smith has small fractures around his eyes along with a concussion, coach Scott Linehan said.

``We haven't counted him out next week, but he'd be highly doubtful,'' Linehan said. ``With those two injuries it's going to take a while before he's going to be cleared.''

Linehan said the facial fractures will heal without surgery.

The Rams signed linebacker Isaiah Kacyvenski, the Seahawks' special teams captain until being released on Saturday, and released safety Dwaine Carpenter.

Offensive tackle Orlando Pace, who missed last Sunday's game with a concussion, did limited work in practice on Wednesday and was listed as questionable.
