Denver signed Keene to its practice squad Saturday, Aric DiLalla of the Broncos' official site reports.
Keene started the season on the Eagles' practice squad after being a casualty of the Patriots' final roster cuts, but he was recently let go by Philadelphia and will get a new opportunity in Denver. The 2020 third-round pick caught three of five targets for 16 yards across six appearances during his rookie season, but he hasn't appeared in an NFL game since.
