On December 7, 2015, he was signed to the Jacksonville Jaguars practice squad where he spent the remainder of the season. In 2016, he spent time on the Jaguars practice squad, was promoted to the active roster and saw action in two games. He was released by the team on May 1, 2017.

A 26-year-old native of Schertz, TX, Porter attended Texas A&M University where he appeared in 52 games (41 starts) and totaled 261 tackles, 14.5 sacks, 13 passes defensed, three fumble recoveries, two forced fumbles and one interception.
