Antonio Grier Jr. Career

South Florida Years (2018–2022)

Grier’s development continued rapidly during his junior season in 2020. Despite playing in only eight games due to schedule adjustments, he posted 59 tackles, 5.5 tackles-for-loss, and 3.0 sacks, earning second-team All-American Athletic Conference honors for the first time. His consistency as a defender became a hallmark of his game, and opposing offenses began keying on his presence within the Bulls’ defensive scheme.

The 2021 season represented the pinnacle of Grier’s time at South Florida. He started all 12 games and delivered a team-leading 92 tackles, complementing this production with eight tackles-for-loss, three sacks, and two interceptions. This exceptional performance earned him a second consecutive second-team All-AAC selection, solidifying his status as one of the conference’s top linebackers. His leadership and playmaking ability became central to South Florida’s defensive identity.

Grier opened the 2022 season with strong early production, recording 21 tackles in the first three games. However, a season-ending hand injury forced him to redshirt, bringing his South Florida career to an abrupt conclusion. Despite the injury setback, his body of work with the Bulls had established him as a professional-level talent.

Arkansas Transfer (2023)

Following the 2022 season, Grier made the decision to transfer to the Arkansas Razorbacks for his final year of college eligibility. The move to the Southeastern Conference represented a significant step up in competition. Remarkably, on his very first play as a Razorback, Grier intercepted a pass and returned it for a touchdown, announcing his arrival in spectacular fashion.

At Arkansas, Grier served as the third linebacker in the rotation, contributing as both a starter and reserve. He finished seventh on the team with 36 tackles during his lone season in Fayetteville. The experience of playing in the SEC against some of the nation’s top offensive talent further prepared him for professional football. After the season concluded, Grier declared for the 2024 NFL Draft, ending his collegiate career on a positive note.

Tampa Bay Buccaneers (2024–2025)

Despite projecting as a potential mid-round selection, Grier went undrafted in the 2024 NFL Draft. The Tampa Bay Buccaneers nonetheless recognized his talent, signing him as an undrafted free agent. His journey with the franchise began with a training camp roster spot, where he competed for a position on the defensive depth chart.

Grier was waived during final roster cuts in August 2024 but was quickly re-signed to the practice squad, maintaining his connection to the organization. He was promoted to the active roster in October, providing depth at linebacker during the regular season. The Buccaneers shuffled their linebacker depth throughout the season, with Grier moving between the active roster and practice squad multiple times. He signed a reserve/future contract in January 2025, indicating the team’s continued interest in his development.

However, on August 26, 2025, the Buccaneers waived Grier with an injury designation as part of their final roster reductions. This marked the end of his tenure with the organization that had given him his first professional opportunity in the NFL.

Louisville Kings Era (2026–Present)

Following his release from Tampa Bay, Grier continued his professional football career by signing with the Louisville Kings of the United Football League on February 19, 2026. The move to the UFL presented a new opportunity to showcase his abilities in a professional spring football league. His addition to the Kings’ roster reflected both his continued dedication to the sport and his belief in his ability to contribute at a high level.

His college production demonstrated consistent tackle numbers and the capacity to make plays behind the line of scrimmage. He possesses the instincts to read plays and close quickly on ball carriers, while also showing coverage ability with his interception totals. His transition to the professional level required adjustment to faster offensive schemes and more sophisticated play designs, challenges he has continued to address throughout his early career.

Notable Achievements and Milestones

The most memorable moment of Grier’s collegiate career came on his very first play at Arkansas, when he intercepted a pass and returned it for a touchdown. This highlight-reel play exemplified his playmaking ability and provided a glimpse of his potential to make game-changing plays at the next level. His two second-team All-AAC selections at South Florida remain the most significant honors of his football career thus far.
