Romo attended the 2003
NFL Combine, but, despite intriguing some scouts, went undrafted by any
NFL team during the
2003 NFL Draft.
Throughout the draft, Romo was assured by Sean Payton of the Cowboys' interest (Romo was also intensely pursued by former Denver Broncos head coach Mike Shanahan),[12] and shortly afterwards was signed as an undrafted rookie free agent by the Cowboys. Romo entered the 2003
training camp third on the Cowboys' depth chart behind
Quincy Carter and
Chad Hutchinson. In 2004, the Cowboys released quarterback Chad Hutchinson and signed veteran quarterback
Vinny Testaverde and traded a third round draft pick to the
Houston Texans for quarterback
Drew Henson. Romo faced being cut from the roster until Quincy Carter was released following allegations of substance abuse. Throughout 2004 and 2005, Romo served as the holder for placekicks.
[6] After Vinny Testaverde's tenure in Dallas ended in 2005, the Cowboys signed veteran quarterback
Drew Bledsoe, the eighth starting quarterback for the Cowboys since 2000.
One of Romo's early career highlights was in 2004, when (as the third string QB) he rushed for the winning touchdown with six seconds left in a preseason game against the Oakland Raiders. Elevated to the Cowboys' #2 quarterback in 2005, Romo had strong showings in the 2005 and 2006 pre-seasons.
In the 2006 off-season, Sean Payton (now head coach of the New Orleans Saints), offered a third round draft pick for Romo, but Jerry Jones refused, asking for no less than a second round draft pick. Romo eventually took over the first-string quarterback role from Drew Bledsoe during half time against the
New York Giants on October 23, 2006.
