Wide receiver Jacoby Ford and cornerback Ron Bartell were placed on injured reserve by the Raiders, who promoted cornerback Coye Francies and long-snapper Nick Guess from the team's practice squad.
Ford underwent foot surgery on Tuesday, while Bartell suffered a fractured shoulder blade in the Week 1 loss to San Diego. Bartell was given the designated to return label, which means he can return to practice Oct. 27 and could return to the team as early as the Nov. 11 game at Baltimore.
Francies was claimed off waivers from Seattle in August, released Sept. 6 and added to the practice squad Wednesday.
Guess, an undrafted rookie out of Tennessee, was also added to the practice squad this week. Pro Bowl long snapper Jon Condo (concussion) was injured against the Chargers, forcing linebacker Travis Goethel to handle the duties for the remainder of the game.
