Aikman took snaps as the starting quarterback for the first time since he was sidelined because of a broken left collarbone during the second quarter of Denver's 42-23 victory over the Cowboys on Sept. 13.
Aikman said he experienced a little pain when throwing, but otherwise felt "pretty good."
"It's the first day. I'll get more practice time tomorrow [today] and next week. I need all the practice I can get. I feel confident about going out and playing," he said.
Aikman's collarbone won't be completely healed until after the season.

"I tried to show I was moving on," Banks said. "By no means was I trying to say I don't care. I think my biggest thing is I care too much. I carry a lot of weight on my shoulders."
