Castañeda was born on 19 January 1983 in the border city of Acuña, Coahuila, Mexico.[2] He began playing American football at the age of 10 with Club Vaqueros de Ciudad Acuña, winning several championships as one of the most competitive teams in AFAINC.[1][2] Castañeda later returned to the Vaqueros organization as a coach in 2020.[2]
Castañeda credited the Monterrey coaches with teaching him the English terminology that he would later use during his pro career.[6] He graduated with a Licentiate degree in international trade.[2][4]
Professional career
Rhein Fire
Castañeda decided to forego his final year of college eligibility, signing with NFL Europe team Rhein Fire in 2007 as an international prospect.[3][7] In his first game as a pro, he logged three tackles against the Berlin Thunder.[8] He played in 10 games in his lone season with the Fire, recording 10 tackles on defense and five on special teams.
In the 2008 offseason, Castañeda focused on improving his speed and his footwork to better adjust to NFL gameplay.[11]
Arizona Cardinals
In his second year in the International Development Practice Squad Program, Castañeda joined the Arizona Cardinals practice squad for the 2008 season.[1][12] His former college teammate, Rolando Cantú, had previously become the first player from a Mexican university to play an NFL regular-season game when he appeared for the Cardinals in 2005.[12]
The Cardinals reached Super Bowl XLIII that year, with Castañeda traveling to Tampa, Florida to support his teammates.[13] The team lost to the Pittsburgh Steelers 27–23. However, Castañeda was heavily sought after by the Latino media on Media Day, with his teammates teasing that he was more famous than Kurt Warner.[14][15] He also received a National Football Conference championship ring in the offseason.[7]
Castañeda continued training for the 2009 season, though he was not offered a contract.[16] He was reported to have signed a free agent deal with the Cleveland Browns in July 2010.[16] However, he did not join the team for preseason.
