Manning was at practice and wore a helmet, but only had mental and walk-through repetitions as he took a rest day similar to the ones he received during OTAs, minicamp and training camp.
"He threw the ball a lot on Monday, so we're going to get him in the routine of how we're going to do it through the course of the season," Head Coach Gary Kubiak said.
Manning didn't throw, but did get mental repetitions.
"I was out there, doing everything that I can, participating in the walk-throughs and the blitzes," he said.
