Keir Thomas Bio
Keir S. Thomas (born January 25, 1998) is an American professional football linebacker for the Los Angeles Rams of the National Football League (NFL). He played college football for the South Carolina Gamecocks and the Florida State Seminoles before joining the NFL as an undrafted free agent in 2022. Standing 6 feet 2 inches tall and weighing 248 pounds, Thomas has built a career as a hard-working defender who has bounced between the active roster and the practice squad while continuing to develop his game.
Early Life and Background
Keir S. Thomas was born on January 25, 1998, in Miami, Florida. He grew up in a region known for producing top-tier football talent and attended Miami Central Senior High School, a program with a strong tradition of developing collegiate and professional players. At Miami Central, Thomas lined up at multiple positions along the defensive front, including nose guard, defensive end, defensive tackle, and linebacker, showing the kind of positional flexibility that would later define his college and professional career.
As a junior, Thomas recorded 71 tackles and 18 sacks, performances that earned him recognition as a PrepStar All-American. He followed that with a senior season in which he posted 22 sacks and 83 tackles, establishing himself as one of the most disruptive defensive players in the state of Florida. Rivals.com ranked him as the 49th-best player in Florida and the 23rd-best strongside defensive end nationally. He was also named a first-team Class 6A all-state player and the Miami Herald 8A-6A Defensive Player of the Year, honors that reflected his dominance at the high school level.
Path to American Football
Thomas’s path to the NFL began in earnest when he committed to the University of South Carolina and enrolled in January 2016, joining the Gamecocks football program as a true freshman. He immediately contributed on the defensive line, appearing in all 13 games during his first season and earning starts in two of them while recording 24 tackles and two sacks. His early production suggested a promising future in the Southeastern Conference and gave him a foundation on which to build.
By his sophomore season in 2017, Thomas had become a regular starter, lining up in 11 of 13 games and totaling 38 tackles and two sacks while playing both on the edge and in the interior of the defensive line. His coach described him as invaluable to the team, a sign of the respect he had earned in the locker room. After a junior year in which he started 12 games and posted 44 tackles with 1.5 sacks, Thomas suffered a serious ankle injury during the 2019 fall camp that led to an infection and kept him out for nearly the entire senior season, limiting him to just two games and four tackles. He was later named one of six winners of the Dr. Harris Pastides Outstanding Student-Athlete Award for his perseverance.

Thomas returned to the field for the South Carolina Gamecocks in 2020 and was one of the team’s top defensive linemen, recording 32 tackles and three sacks while continuing to manage the effects of his prior injury.

In his only season with the Florida State Seminoles, Thomas started all 12 games, posted 42 tackles including 12 tackles for loss, 6.5 sacks, and 15 quarterback hurries.

Los Angeles Rams Debut (2022)
Thomas was not invited to the NFL Combine and went unselected in the 2022 NFL Draft. On May 1, 2022, he signed with the Los Angeles Rams as an undrafted free agent, beginning his professional career with one of the league’s most recognizable franchises. He impressed during training camp and delivered a strong performance in the final preseason game, which helped him earn one of three undrafted rookie spots on the Rams’ final roster.
Thomas made his NFL debut in Week One of the 2022 regular season, appearing on one defensive snap and 11 special teams snaps in the Rams’ 31–10 loss to the Buffalo Bills. He was waived by the Rams on September 22, 2022, but was re-signed to the practice squad two days later. The Rams promoted him back to the active roster on December 3, 2022, providing him with an opportunity to finish his rookie season with the team.
Los Angeles Rams Tenure (2023–Present)
On August 29, 2023, the Rams waived Thomas and re-signed him to the practice squad, a pattern that would repeat itself as he continued to work toward a permanent role on the active roster. He was signed back to the active roster on November 14, 2023, and remained with the organization through the end of the season. The following year, on August 27, 2024, the Rams again waived Thomas and re-signed him to the practice squad, demonstrating the team’s continued interest in his development.
Thomas signed a reserve/future contract with the Rams on January 20, 2025, securing his place with the organization for the upcoming league year. His tenure with the franchise has been defined by persistence, as he has repeatedly earned promotions from the practice squad through strong practice and preseason performances.
Driving Style and Strengths
Thomas has shown the ability to play multiple positions along the defensive front, including defensive end, defensive tackle, and linebacker, both at the college and professional levels. His college production in tackles for loss, sacks, and quarterback hurries at Florida State highlighted his ability to disrupt plays in the backfield, while his special-teams work with the Rams has reflected the kind of versatility teams look for in a developmental defender.
Notable Events and Milestones
One of the most significant milestones in Thomas’s career came in 2022, when he became one of only three undrafted rookies to make the Rams’ final roster, a notable achievement for a player who had not been invited to the NFL Combine. His selection as a team captain at Florida State in 2021 and his third-team All-ACC honor that same season stand as the highest recognition of his college career.

2025 Season Performance
Keir S. Thomas began the 2025 league year with the Los Angeles Rams after signing a reserve/future contract on January 20, 2025, a deal that tied him to the franchise following the conclusion of the 2024 season. The agreement gave him the opportunity to compete for a roster spot during the Rams’ 2025 offseason program and training camp. On August 19, 2025, Thomas was placed on injured reserve, an early-season setback that limited his availability for the start of the campaign.
Thomas’s 2025 outlook had been shaped by his continued growth within the Rams’ defensive system and his track record of earning promotions from the practice squad to the active roster in previous seasons. The Rams have shown continued faith in his versatility along the defensive front and on special teams, areas where he built his reputation at both the college and professional levels. With his placement on injured reserve, his return to the field in 2025 will depend on his recovery timeline and the team’s roster needs later in the season.
