New Bears offensive lineman Chris Spencer took snaps with the starters Wednesday, but only after starting right guard Lance Louis got ill during practice.
Spencer stepped in at center, and Roberto Garza swung over to right guard.
"We kind of got lucky, a little bit. Lance is going to be OK," Bears offensive line coach Mike Tice said. "It's nice to take a look, without turning it into a saga."
Bears offensive coordinator Mike Martz said the offensive line was only responsible for three of the nine sacks allowed against the Buffalo Bills. But, the Bears expect the offensive line to take a step forward, against the New York Giants next Monday at the New Meadowlands.
"We should still be embarrassed by that," Tice said, referring to the Oct. 3 game in which quarterback Jay Cutler was sacked nine times on 21 drop backs in the first half of a 17-3 loss to the Giants. "Now, you have a chance to go in there and play better and redeem yourself, to some extent - I mean, it is a preseason game - but they're not going to be balls to the wall with blitzes and those sort of things.
"But it'll be a great challenge for us physically."
While he knows the move isn't permanent, Spencer said he enjoyed getting to work with the starters.
"It was good. Just get comfortable with the guys, and knowing what they're doing and letting them hear my voice and my calls," he said.
Spencer said he's getting very comfortable with the offense, and he's able to make all the calls without any help.
