Allen was limited in Wednesday's practice with a broken right foot, according to the practice report released by pool reporter Jarrett Bell of USA Today, the same injury that kept him out of the NFC Championship Game.\
But according to coach Ron Rivera, the move was precautionary.
"Jared's was really about rest," Rivera said. "He's been going full blast since we started, and the doctors wanted to just make sure. So he earned the rest."
Davis, who suffered a broken forearm in the NFC title game, was a full participant Wednesday. He wore a protective cast over the injury, which required a metal plate with about a dozen screws.
The Panthers practiced for an hour and 15 minutes on the grass fields adjacent to San Jose State's Spartan Stadium in preparation for Sunday's game against the Denver Broncos.
Rivera said Davis will have his arm examined by doctors again on Friday, but the full practice load was a clear indication he will be ready for Sunday.
"When the doctors say he's 100 percent, I'll go with it," Rivera said.
Wednesday's session was about fine-tuning details of the game plan the team implemented last week in Charlotte, North Carolina.
Crowd noise was pumped in as the first-team offense worked against the scout team.
Cam Newton had a solid day throwing. None of his passes during team drills hit the ground.
"That's our quarterback," Rivera said. "The interesting thing is that he builds onto it as the week progresses. He was sharp today, but wait until you see him Thursday and Friday."
