CHARLOTTE, N.C. — The Carolina Panthers will be without top receiver Steve Smith and starting safety Sherrod Martin against Chicago because of injuries.

Smith hasn’t practiced since spraining his left ankle in Sunday’s loss to New Orleans and has been in a protective boot this week. Martin has been sidelined since sustaining a concussion against the Saints.

Linebacker Jamar Williams and right tackle Jeff Otah also won’t play Sunday against the Bears. Williams has a neck injury and Otah hasn’t played or practiced all season because of a knee problem.

Running back DeAngelo Williams practiced for the second straight day Friday following an illness and is probable for Sunday. Cornerback Captain Munnerlyn practiced and is probable despite a sore foot.
