The Chargers signed defensive lineman Andrew Brown and linebacker Josh Watson to the practice squad on Wednesday, the team announced.
After promoting defensive tackles Forrest Merrill and Breiden Fehoko from the practice squad to the active roster, it left two vacant spots.
Brown, a fifth-round pick by the Bengals in 2018, played in 21 games over his first three seasons, 18 with Cincinnati and three with the Texans. He was on the Colts prior to being released ahead of the 2021 season.
In that time period, he posted 17 tackles, one sack, one tackle for loss, and three quarterback hits.
Watson, on the other hand, played his collegiate career at Colorado State before being signed as an undrafted free agent by the Broncos in 2019. In two seasons, he appeared in 17 games and totaled seven sacks.
