The Monterrey Steel was a professional indoor football team and a charter member of the National Arena League (NAL) that played in the 2017 season.

On November 30, 2016, it was announced that the Monterrey Steel would be joining the National Arena League for its inaugural 2017 season.

They again faced the Sharks in Jacksonville one week later in a semifinal playoff game, where they lost 43–32.

During the 2017 off-season, the Steel were unable to commit for playing the 2018 season in the NAL citing the 2017 Central Mexico earthquake.
