Take nothing away from Greg Gumbel or Dan Dierdorf. Their broadcast team is as good as it gets. But the game Sunday at Cincinnati snaps a streak of 12 consecutive games when the Broncos drew the networks’ “A” broadcast team.

That’s the longest streak since the Dallas Cowboys — who in many ways are considered America’s Team by the networks — from 2009-10.

The Broncos’ run began when CBS’s top team of Jim Nantz and Phil Simms descended upon Tebowmania for the final five games (counting two playoff contests) of Denver’s 2011 season.

The Nantz-Simms team also called three Broncos games this season: against Houston, Oakland and New England. The Broncos with Peyton Manning this year already have had two Sunday night games with Al Michaels and Cris Collinsworth and two Monday night games with Mike Tirico and Jon Gruden.

The last time the Broncos didn’t draw the “A” broadcast team was when Fox sent its No. 2 tandem of Kenny Albert and Daryl Johnston to call their 13-10 overtime victory against quarterback Caleb Hanie’s Chicago Bears last December.

Gumbel and Dierdorf are CBS’s No. 2 broadcast team. The Broncos are only 2-6 during their recent run with Nantz and Simms, so the team figures to welcome Gumbel and Dierdorf with a smile.

Broncos replace Mays with Ihenacho. There was a mild surprise among the Broncos’ roster transactions Tuesday.

Not a surprise was the placement of middle linebacker Joe Mays on injured reserve. Mays suffered a fractured left fibula near the ankle Sunday night while blocking on a fourth-quarter punt return.

What was somewhat unexpected was the Broncos replaced him on the 53-man roster not by promoting middle linebacker Mike Mohamed from the practice squad, but safety Duke Ihenacho.

The Broncos like Ihenacho, an undrafted rookie who gives them a little more special-teams speed and has been with the team all season — five weeks on the practice squad and two weeks on the active roster.

The Broncos will receive additional linebacker depth in two weeks when the last of D.J. Williams’ two suspensions is lifted.

To fill Ihenacho’s spot on the practice squad, the Broncos signed cornerback Mario Butler. A former Georgia Tech teammate of Broncos receiver Demaryius Thomas, Butler was undrafted in 2011 but was signed to the Cowboys’ practice squad.

Footnotes. The Broncos’ Wesley Woodyard and Cleveland linebacker D’Qwell Jackson are the only two NFL players who have at least 50 tackles, three sacks and two interceptions through Week 8. … Yes, the Broncos are getting closer to becoming a complete team. Their offense ranks third (405.4 yards per game), their defense is eighth (319.3 yards per), kicker Matt Prater is 9-for-9 on field-goal attempts and punter Britton Colquitt is fifth in net punting (42.6) and first in return average (4.5 yards).
