Bulaga was wearing a brace Wednesday on the left knee that he injured at Chicago in Week 3, and it's not clear if he'll be able to play Sunday against the St. Louis Rams.
"(I) had a chance to watch him a little bit, he was working with a brace, and I think the biggest thing is to watch the tape and see how he feels tomorrow," Packers coach Mike McCarthy said. "But he looked like he's moving fine, but the progression is to take him limited and see how he is tomorrow."
"I don't want to talk about it," he said.
McCarthy said Dominguez likely will provide depth on the interior while Bulaga, Newhouse and Sherrod rotate at tackle in practice this week.
"I think it's important to rotate all three of those tackles," McCarthy said. "Marshall's played really good football for us the last two weeks. Bryan will come back here, we'll try to get him ready at right tackle, and Derek's been playing both."
