Brown joined the Cleveland Browns in 2022 as an undrafted free agent. He appeared in just three games for the Browns, recording a single tackle. The Titans signed Brown from Cleveland's practice squad in January 2023, and in 2024, he stepped up in a big way when Quandre Diggs was lost for the season.

Brown played all 17 regular-season games with Tennessee in 2024, including four starts. He also contributed consistently on special teams. Now, as he heads into his age-26 season, Brown could get a chance to compete for a more substantial rotational role on defense this offseason.
