It won't go on his personal list of accomplishments, but Peyton Manning helped set another record as the Broncos reported a record 4,372 people came to their Dove Valley headquarters for the team's first practice of training camp.

Manning drew huge cheers for scrambling out of the pocket on one play -- but don't expect the Tim Tebow read-option offense to return. Among Manning's passing highlights were long gainers to Andre Caldwell and Greg Orton.

Right guard Chris Kuper and running back Knowshon Moreno, both coming off serious injuries, participated while former Manning buddy Brandon Stokley sat out with the flu.
