The Broncos are concerned enough about their kickoff length to at least bring Brandon McManus back into the building.

He’s not on the 53-man roster, but McManus has been re-signed to the Broncos’ practice squad. To make room for McManus, the Broncos released defensive end Gerald Rivers from their practice squad.

McManus was the Broncos’ place-kicker for their first 11 games. He was waived after making a league-low 69.2 percent of his field-goal attempts (69.2). However, McManus was strong on kickoffs, as he had a 75 percent touchback rate that ranked third in the league.

The Broncos signed veteran Connor Barth to handle their kickoff duties, and in his debut last Sunday at Kansas City, he tied a team record by making five of five field goals.

However, Barth was short on his kickoffs as the Chiefs started between their own 31- and 38-yard line on their first seven returns.On his eighth kickoff, Barth’s boot landed at Chiefs’ 13-yard line and his coverage team came through by limiting the return to the 24.

Broncos coach John Fox had said earlier in the week that the frigid, windy conditions in Kansas City were not a fair evaluation for Barth. But apparently they want McManus back in the building so he can be available on moment’s notice.
