"It's tough," Cutler said Wednesday. "This league is all about battling through injuries. But obviously, concussions and your head is something you have to take pretty seriously."
Cutler said he felt good enough to play at Carolina, but extra caution was taken.
"Concussions are kind of tricky," Cutler said. "You're never really for sure when you're 100 percent healthy. ... Everyone thought it would be better if I waited another week."
Cutler, who said the concussion was his first, wasn't sure when the injury occurred. He had taken several big hits before Ross' sack and acknowledged, "There were some moments in the second quarter where I wasn't completely aware of what was going on."
Cutler got up and took a few steps toward the wrong sideline before correcting himself. Soon after, he had what appeared to be a dazed look when television cameras showed him sitting on the sideline, and his decision-making was questionable.
Cutler held onto the ball too long at times, with most of those sacks coming on four-man rushes, and Collins was behind center when the second half started.
"We just had some breakdowns," Cutler said.
Cutler said he could have avoided some of the sacks, although his wooziness played a role.
"I don't think it helped," he said. "But I think I still knew what was going on. I still knew what the hot reads were, still knew where guys were at in the field."
Cutler said the concussion had no effect on his diabetes, and he doesn't anticipate seeing the doctors again before Sunday's game.
"It's tough," he said. "You think you feel OK. It's just so hard with your brain. Those second concussions are the ones that are a little tricky."
It would help if Cutler had better protection -- a big issue the past few seasons.
Garza is set to have arthroscopic surgery and will miss the Seattle game. Williams is back after missing the last three games, and there's no guarantee he'll be back at left tackle.
Bears offensive coordinator Mike Martz indicated Williams could be moved inside, saying: "He's natural inside because he's so stout, and that helps us in protections and in the running game, obviously, too. We just need to get our best guys on the field that are healthy and ready to go."
