The Dolphins confirmed the news on Sunday and announced that they’ve waived OT Nick Kaltamayer and activated DT Brandin Bryant from the COVID-19 list.
Colbert, 26, is a former seventh-round pick of the 49ers back in 2017. He was in the second year of his four-year, $2.48 million contract when the 49ers placed him on injured reserve coming out of the preseason.
San Francisco later waived Colbert with an injury settlement and he signed on to the Seahawks’ practice squad in 2019. He bounced on and off Seattle’s practice squad before Miami signed him to their active roster.
The Dolphins re-signed Colbert to a one-year, $1.775 million deal this past March.
In 2019, Colbert appeared in six games for the Dolphins and recorded 22 tackles, no interceptions and two passes defended.
