The St. Louis Rams faced San Francisco on Sunday without wide receiver Danny Amendola.
Amendola was declared inactive before the game by the Rams because of a foot injury. After sitting out of practice during the week, there was hope that he would play against the 49ers after a walking boot was removed Friday.
Amendola missed most of last Sunday's win over Arizona and was sidelined for three games earlier in the season because of a clavicle injury.
The fourth-year pro has 51 catches for 576 yards and two touchdowns this season.
