Eastern Illinois (1999–2002)
Dallas Cowboys (2003–2016)
Then there is this:
Romo did not initially receive an invitation to attend the 2003 NFL Combine, but received a late invitation to attend as an extra quarterback to throw passes to other prospects during drills. Despite intriguing some scouts, he went undrafted by any NFL team during the 2003 NFL draft. Throughout the draft, Romo was assured by Dallas assistant head coach Sean Payton of the Cowboys' interest (Romo was also intensely pursued by Denver Broncos head coach Mike Shanahan), and shortly afterwards was signed as an undrafted rookie free agent by the Dallas Cowboys. Romo entered the 2003 training camp third on the Cowboys' depth chart behind Quincy Carter and Chad Hutchinson.
