He would earn a spot on the Chargers roster in 2003 with his impressive performances in training camp, despite having not even been initially recruited by a major college.
He would last two years with the Chargers, and four years in the League overall, also being signed by the Denver Broncos, and later the Tennessee Titans.
Knee problems would limit his effectiveness and chances of game action in later years. Mattos appeared on, the 22nd season of the reality television competition Survivor.
On the Ometepe tribe, Mattos quickly formed a close friendship and strong alliance with eventual winner Rob Mariano. On Day 35, after intended target Ashley Underwood won the Immunity/Reward Challenge, Mattos was blindsided and voted out, as he was deemed by Rob and the other tribe mates to be the largest threat to win the jury"s vote at the end of the game. Mattos later voted for Mariano to win the game over fellow former Ometepe members Natalie Tenerelli and Phillip Sheppard.
When the tribes merged, the former Ometepe members outnumbered the members of the opposing Zapatera tribe, and used their majority to systematically eliminate those outside their alliance. The following day, he lost the Redemption Island challenge to return to the game, and finished the game in eighth place, as the fifth member of the jury.
