"If that's the case (starting at right tackle against the Rams), you know it's something I've been working for all year, starting with training camp and everything," Shaffer said. "Right tackle is my position that I've been at for the last couple of years, so that would be great."
A groin injury to Orlando Pace forced Shaffer into action at left tackle last Sunday in Minnesota.
"He did a nice job," Bears offensive coordinator Ron Turner said. "He stepped in and did a nice job. He has some playing experience, so it's not totally new for him. I thought he stepped in and did a good job."
