"Max had a good day [Monday]," Carroll said "He got hit in the head [in Sunday's game] and Red did as well, as we found out today. They both will go through the [concussion] protocol to see if they are able to return [to play this weekend]. We'll take great care in making those decisions."
Carroll also was asked about receiver Percy Harvin's status to return this weekend at Atlanta.
"I don't know that, but I'm not counting on that," Carroll said. "We'll see. We're still working to bring him back, and he had a good rehab work [Monday]."
Okung can't come off injured reserve until Nov. 17, so it's possible both starting offensive tackles could come back for the home game against Minnesota that day.
"Breno could play this week, but it's not likely he'll be ready," Carroll said. "It's a lot to ask in one week on the practice field. We'll take a couple of weeks to get his legs under him."
Giacomini had arthroscopic knee surgery Sept. 30th. Okung has a torn ligament in a big toe. Both players worked out on the field before Sunday's game against Tampa Bay.
