ENGLEWOOD, Colo. (AP) As an 85,000-square-foot indoor practice facility rises in the background of the Denver Broncos' training complex, fourth-year safety Quinton Carter not so quietly goes about resurrecting his NFL career.

The two projects are intertwined.

Carter missed most of the last two seasons after getting hurt inside the team's rented practice bubble during a rainstorm two summers ago, blowing out a hamstring and a knee while avoiding a soccer goal after defending a deep pass from Peyton Manning to Eric Decker.

After starting 10 games as a rookie in 2011 and intercepting Ben Roethlisberger and Tom Brady in the playoffs, Carter needed microfracture surgery following his injury inside the practice bubble, which doesn't have regulation size fields like the new facilities will.
