Professional career

Houston Texans

The Houston Texans selected Swearinger in the second round, with the 57th overall pick, of the 2013 NFL Draft. On the 13th of October 2013 in a game against the St. Louis Rams, the Houston Texans starting strong safety Danieal Manning was injured with a hairline fracture of his right fibula, which meant that the rookie safety would get his first start against Kansas City Chiefs the week after, he finished the game with a total of 5 combined tackles. He was waived on May 11, 2015.

Preseason controversies

On August 17, 2013, Swearinger hit Miami Dolphins tight end Dustin Keller's right knee, tearing his ACL, MCL, and PCL, and also dislocating his knee. While some players considered the hit as "dirty", Swearinger stated that he went low to avoid a fine and the player was not reprimanded by the NFL.

In the next preseason, on August 23, 2014, Swearinger was on the spotlights again in a match against the Denver Broncos after a hit that caused a concussion in wide receiver Wes Welker and drew an "unnecessary roughness" penalty. On the next play, Broncos quarterback Peyton Manning confronted the safety after completing a touchdown pass to Emmanuel Sanders, later resulting in Manning's first fine in his NFL career. Once again, Swearinger was not fined.

Tampa Bay Buccaneers

Swearinger was claimed off waivers by the Tampa Bay Buccaneers on May 12, 2015. On November 17, 2015, he was waived.

Arizona Cardinals

Swearinger was signed to the Cardinals practice squad on December 1, 2015. He was promoted to the 53-man roster on December 8, 2015. Due to injuries in the Cardinals defensive backfield, Swearinger started his first game for the Cardinals on December 20, 2015. The next week, he started again against the Green Bay Packers, and would make a big impact, forcing a fumble against running back James Starks.
