For the moment, Arlen Harris is the starting Rams running back. Freshly signed
Aveion Cason is his replacement as the kickoff returner.

Rookie running back Steven Jackson rested his swollen and bruised knee at
practice Wednesday. And Marshall Faulk is still resting his bruised knee after
sitting out Sunday's victory over the *****.

Coach Mike Martz figures both Jackson and Faulk could be ready to play at
Carolina on Sunday, but he'll know more later in the week.

"It's hard to start (Jackson) if he doesn't practice," Martz said. "I think
he'll be ready on Sunday. I'd like to get him some (practice) Friday and maybe
a little tomorrow.

"I believe we'll have Marshall, too."

Harris started two games at running back last season when Faulk was injured,
including an 81-yard, three-TD effort at Pittsburgh.

With Harris getting all the work at running back in practice, Cason will
prepare to return kicks Sunday. He briefly filled that role for the Rams back
in 2001 before getting released.

After stints with the Chiefs, Lions, Cowboys and Cardinals, Cason is getting
another look in St. Louis. He will also provide depth at running back should
Faulk or Jackson fail to progress.
