The St. Louis Rams are preparing as if Nick Foles will start Sunday against the Cincinnati Bengals.
Head coach Jeff Fisher announced Friday that Case Keenum has yet to be cleared from the concussion he suffered in last Sunday's loss to the Baltimore Ravens.
Fisher said the Rams will evaluate Keenum again Saturday before making a final decision on their starting passer.
Foles started the Rams' first nine games of the season, completing 56.6 percent of his passes for 1,678 yards, seven touchdowns, and six interceptions.
