Tony Romo has enjoyed a remarkable three-year tenure in the NFL broadcast booth for CBS, but the media giant may have to pay up a pretty penny to keep him around long-term.

According to a report from Michael McCarthy (not the new Dallas Cowboys head coach) of Front Office Sports, ESPN will prepare to offer Romo a contract that would give the former Pro Bowl quarterback "between $10 million to $14 million annually."

Per McCarthy, such a deal would make the 39-year-old "the highest-paid sportscaster in TV history." It was noted by McCarthy that ESPN wouldn't comment on the matter.

Romo was the starting quarterback of the Cowboys from 2006 to 2016 until injuries derailed his career. Following a preseason injury to Romo in 2016, rookie Dak Prescott took over as the starter -- and he played well enough to secure the starting job the rest of the way.

Romo then decided to retire from football, and he joins CBS' top NFL announcer Jim Nantz in the booth, replacing the latter's long time partner in Phil Simms.

Nantz and Romo called Super Bowl LIII between the New England Patriots and the Los Angeles Rams last year. Their final assignment for the 2019 NFL season takes place this Sunday -- in the AFC Championship Game where the Kansas City Chiefs will host the Tennessee Titans.

McCarthy noted that Romo is taking home around $4 million this year. In comparison, Fox analyst Troy Aikman -- also a former Cowboys Pro Bowl quarterback -- takes home around $7.5 million per year, per McCarthy.

ESPN's NFL commentary team consists of play-by-plan man Joe Tessitore and two-time Super Bowl champion Booger McFarland. The Monday Night Football commentary team saw a shakeup after the 2017 season, when Sean McDonough went back to only calling college games. Analyst Jon Gruden left to rejoin the Oakland Raiders as their head coach, inking a $100 million contrct.
