The Dallas Cowboys' signing of Mark Sanchez while keeping Tony Romo on the team's active roster despite a broken bone in his back put the team in a unique position. Two quarterbacks of Mexican heritage are now on a single NFL team's active roster.

Sanchez may not see playing time over talented rookie Dak Prescott, but he serves as insurance for Dallas if Prescott falters while Romo is injured.

It was Tony Romo's paternal grandfather, Ramiro Sr., who first came to the United States from Múzquiz, Coahuila, Mexico. His grandparents still attend Cowboys games when they can make it up from San Antonio, Texas. Romo has been, when healthy, the Cowboys' starting quarterback since 2006.

Similarly, Mark Sanchez's Mexican heritage comes from his grandparents -- on both sides of his family. His road in the NFL has been a rougher one than Romo's, and he hasn't started regularly for a team since 2012. His most recent stint in Denver ended with him being beaten out on the roster by Trevor Siemian and Paxton Lynch.

Tom Flores, born to two field-worker parents who emigrated from Chihuahua, Mexico, was the first Latino quarterback to play in the AFL. Flores won a Super Bowl as a backup quarterback in 1970, then won twice as a head coach of the Raiders (1980 and 1983), when Mexican-American Jim Plunkett was the starting quarterback.
