Antonio Ramiro Romo(born April 21, 1980 in San Diego, California) is an American football quarterback who plays for the Dallas Cowboys of the National Football League. He was signed by the Cowboys as an undrafted free agent in 2003. He played college football at Eastern Illinois. 

Romo attended the 2003 NFL Combine, but, despite intriguing some scouts, went undrafted during the 2003 NFL Draft. Throughout the draft, Romo was assured by Sean Payton of the Cowboys' interest (Romo was also intensely pursued by Denver head coach Mike Shanahan), 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. 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 3rd string QB) he rushed for the winning TD with 6 seconds left in an exhibition contest 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 starting quarterback role from Drew Bledsoe during half time against the New York Giants on October 23, 2006.  (via Wikipedia)
