Huerta attended the University of Miami, where he was a walk-on kicker for the Miami Hurricanes football team from 1988 to 1991. During his four years as a starter, he led the Hurricanes in scoring. He still holds the Hurricanes career records for points after touchdowns (PATs), field goals, and total points, as well as the top three season records for consecutive PATs in a season, the top four season records for field goals, and the top three season records for points scored kicking and field goals in a game. As a senior in 1991, he was recognized as a consensus first-team All-American, having earned first-team honors from the Associated Press, the Walter Camp Football Foundation, Football News and The Sporting News.
He graduated from the university with a bachelor's degree in business administration, and was later inducted into the University of Miami Sports Hall of Fame.
While at Miami, he was given the nickname "The Iceman" because of how cool he stayed no matter what the situation.
Huerta joined the Las Vegas Posse, a Canadian Football League expansion franchise. He was one of the few notable players for the Possee, completing 38 of 46 field goal attempts, scoring 154 points. Following the season, he was the recipient of the Jackie Parker Trophy, and was the runner-up for the CFL's Most Outstanding Rookie Award. After the Las Vegas CFL franchise folded, he moved to the CFL's Baltimore Stallions, where he completed 57 field goals and scored 228 points, and was a key contributor to the Stallions' 1995 Grey Cup championship season. His 57 completed field goals remains the second highest season total in CFL history.
