Jim Nantz and Tony Romo found themselves at the center of a CBS broadcast blunder during a pivotal moment in the AFC Championship.

Interestingly enough, Kevin Harlan and Devin McCourty, calling the game for Westwood One Radio, also said there was a flag on the play, with McCourty speculating that it was for Bills offensive lineman Dion Dawkins taking his helmet off.

“There is a flag,” CBS play-by-play standby Jim Nantz announced to the masses watching at home. Kevin Harlan, calling the game for Westwood One Radio, echoed the call. Except, no penalty had been called. The play would count. The Kansas City Chiefs were one clock-killing drive away from a third straight Super Bowl.

The Buffalo Bills' chances of beating the Kansas City Chiefs and advancing to the Super Bowl for the first time in over 30 years came to a crushing end when Josh Allen's desperate heave on fourth down with just two under minutes in the game fell to the ground.

Broadcaster Jim Nantz lucked into calling Tom Brady versus Peyton Manning and Patrick Mahomes versus Josh Allen duels.

CBS Sports begins its 68th consecutive year broadcasting the PGA Tour this weekend with the Farmers Insurance Open at Torrey Pines, which, in itself, is an “Eye”-popping figure, to borrow some network terminology. For nearly two-thirds of that run, Jim Nantz has been a mainstay in the network’s golf coverage.

For a few seconds Sunday night, Jim Nantz — and the CBS scorebug — gave the Bills some hope during the fourth quarter of their AFC championship clash against the Chiefs at Arrowhead Stadium. Josh Allen’s final heave that went through the hands of a diving Dalton Kincaid had fallen incomplete.

David Berson, president and CEO of CBS Sports, said it was critical to hear from a player who is a major winner and a former world No. 1.

CBS lead NFL director Mike Arnold said his team scouts suites before the game to see which camera can get the best shot of a luxury box. Things such as glare, time of day and if the window is up or down all play a role regarding which camera operator is assigned.

Viewers were left confused when the "flag" graphic popped up on the screen following what became the Bills' final offensive play of the contest even though no penalty had been called.
